Help with scary med effects!

This is going to sound very weird, and I know the first thing is to "call your doctor" but i wanted to ask you guys this as well to see what your opinion on this could be.

i've been on the same medication, oxycodone for over a year now. my dosage has not changed and i have not wanted it to change because i'm managing fine with what i have and with my malabsorption issues, dosing can be very tricky.

however, lately... the time i take my late afternoon/evening meds dose, i start to feel really shakey, a little nasueas, VERY lethargic feeling- weak and heavy feeling throughout my body, and then also have been getting these body aches all over my legs and arms and very shallow breathing.. heavy-like.. its just so weird. not to mention, it comes with headaches too. This always happens almost exactly 2 hours after me taking my 5mgs of oxy. I time it every night and have to be aware that i become very ill at this time. I have asked my doc and he has no clue... I sound crazy for bringing this up to anyone anymore since i'm a hard patient to treat due to my sensitivities, regardless, so i'm a little hopless and i just deal with it.
I wait about 2 hours feeling like this death-thing until i take my nighttime valium meds and it knocks me out and gets me through the night until the morning.
So my question is this....its truly not the med itself because i have been on it and its fine in the morning and afternoon.. this ONLY happens on my last dose, 2 hours after taking it.
I was thinking of taking a little smaller dose when this starts, like half, and see if its mini-withdrawls i'm experiencing. I just started trying this a day or 2 ago- and i end up usually vomitting and being SO WORSE than i was before... my body almost completely shuts down after getting sick.. Thats the weird part too.
I'm so sorry for going off, but i'm thinking maybe someone out there might shed their good 2 cents and help me out..
I'm sorry for writing a book- i know thats annoying.. but i had to tell everything so you guys know the whole picture.

Again, I've already heard the docs.. and changing meds isn't the option. I've done that, plus its just not the option or the question in my post.
Thank you to ANYONE who can offer me their opinions

JD23, I'm sorry that you are dealing with all of this! Not feeling well, on top of not knowing why, is frustrating...I've been there.

Keep in mind, this is just my opinion... but I've been on lots of meds, and have had many different experiences. From reading what you wrote, I would "think" that if were just the medication...you'd be feeling this way after every dose. I have felt exactly as you described from medications, so it could be a possibility that it is the oxy.... but when I've felt this way due to meds, I've felt this way whenever I would take them. That being said, it could be that the med sort of "builds up" in your body through the day and makes you sick towards the end of the day... I don't know??

The other thing that makes me think it could be something other than the meds is that you seem to have been on the oxy for a year...am I reading that right? Anytime that I would have side effects from meds, it would be pretty soon after starting them. Not that a reaction can't start after being on a med a long time.....but I would think you would have felt that way before now.

You seem pretty sure that you want to stay on this medication/dose... Have you talked to your doctor about treating the symptoms of whatever this is? For instance, there are some meds that do work well for me but they do bring on massive nausea for me...and my doc will give me a script for Phenergan (nausea/vomiting med). Do you think your doc would be adapt to help treat some of the things you are experiencing?

Sorry, don't know how much help I've been....but that's about all I can think of for now. I DO hope you feel better - like I said, it's frustrating not knowing "why" something is happening!

How are you taking your meds through out the day. Do you take them with food sometimes and on an empty stomach other times? This might offer a clue as to why you are feeling shaky.

Hi

I'm pretty sure you're going to say 'no' , but I'll just double check anyway - I know your dose of Oxy hasn't changed, I'm just wondering if anything else has been added to your regime in the evening (i.e. any other new meds)?

I ask because I have trouble with Oxy and it seems to be triggered by my Fluoxetine - it only happens with the morning dose of Oxy, because that's when I take the Fluoxetine. The only way I can describe it is that the Fluo seems to 'turn off' the Oxy, and I get the muscle cramps and dizziness that I used to get when my body was running low on Tramadol (also an opiate). If I take the Flu an hour before the Oxy, it helps, though I reckon I'm still only getting about 75% efectiveness from the Oxy.

Just wondering if you might be having a similar problem, though I'm sure you'd have mentioned if anything else had changed, so probably not. Just a thought, sorry can't be more help...
