I finished the course I mentioned above of Doxycycline, and went back to the Doc who prescribed it.
I sorta let slip that I had missed the last 3 doses of the pills, cause I misplaced them, then found them, so the course was sorta put out of whack.
The Doc then said I had to take one more week of the stuff to make sure its had the desired effect.
This time, he said I can take the two pills at the same time during the day with food. When I told him about the Depression I was feeling, he said that Depression isnt one of the Symptoms or Side Effects of DoxyCycline, and he said that maybe I was just feeling depressed as result of another side effect. Eg - Maybe the upset tummy was making me upset or somthing?
Anyhow, I noticed for the 1st day, that when taking 2 pills at same time, the depression hits you faster, and harder, its more noticable, I ended up holding my head in my hands for about 10-20 minutes when it hit me, then lying on my bed lifeless, and bored out of my skull.
The second day wasnt so bad, but I did experience some pain in my chest, which I believe is a 'real' recognised side effect of doxycycline. It was like a numb pain, that was constantly there for few hours in my right side of my chest, and it hurt more when I exhaled. Told doctor about it, he thought nothing of it.
In the end, after the 3rd day, I didnt notice much depression or pain. Maybe I had just got used to it. Now im off the stuff, and hoping I never have to go back onto it again. I blame my genetic makeup.... for making me Allergic to Penecillan, hense Doxycycline being prescribed as an alternative.
