Remicade side effects?

I had my first Remicade infusion on 5/31/2013 and it went great.  I was a bit tired afterward, but I blame that on the premeds.  The day after the infusion (Saturday) I felt perfectly fine too, and I spent all day at the driving range.  However, on Sunday I felt like I had been hit by a truck.  I would describe the feeling as a pretty nasty hangover.  Headache, weakness, nausea, and overall general malaise.  It has now nearly been a week since my infusion and I am still feeling a bit weak and tired and I haven't had much of an appetite.  I am in good physical shape - I lift weights and do cardio 3-4 times a week usually even when flaring.  All this week I haven't had the energy to go to the gym, and I get downright dizzy when I climb a flight of stairs.  I seem to be sucking wind all the time. 

I've read the brochures explaining the symptoms/signs of a reaction and dizziness and malaise generally present themselves as symptoms during the infusion or directly afterwards.  So I am confused as to why I felt super on Saturday if this is just the Remicade.  Do you guys thing this can this likely be attributed to my infusion last week?  If any of you have experienced similar symptoms, when did yours subside?  My second loading dose is scheduled for the 14th of this month and I'm concerned that if I am having somewhat of a reaction now I will make it worse by piling on more Remicade.  I would mention it to my doctor, but I am assuming that we can't necessarily attribute my feelings to the Remicade plus it seems to have really helped my UC after only one dose and it's not like I am dying or anything.

I would wait.

A few hours after each of my first two loading doses, I got SUPER sleepy (like, I was falling asleep on the T trying to get home), but that hasn't happened since my second loading dose.

I felt GREAT after my most recent infusion a week ago until Monday, when I woke up feeling as if I'd been filled with lead. The fatigue is finally starting to lessen, but it's still present.

I tend to get very bad fatigue both as a symptom of colitis AND as a sign of healing. I'm going to assume that I'm tired because my body is spending energy on healing my colon.

My first doses were like this. I just came home and nap time! :)

I am never offered any Benadryl or Tylenol for my infusions, which is weird because my doctor TOLD me that the hospital's infusion center would give me both.

I'm not gonna complain, though, since 1) I'm never in any pain, 2) I already take an antihistamine daily, and 3) Benadryl knocks me out so much that I would have trouble getting home afterwards.

I had reactions all over the board until I was on it for about 6months or so. I agree, give it more time and see how you feel. If you keep getting the same reactions, perhaps ask your doc to give you different pre-meds to see if it helps. Right now, I'm on Benadryl (oral) and IV Solumedrol before each infusion and that combo works for me.

But after you've been on it for a while, the side effects should lessen. Normally after my infusions, I'm tired the day of (because of the Benadryl) but afterwards I don't have much issue other than slight thigh and stomach cramps.
