Doxy -- I've been on doxy 100 mg twice a day for three weeks, trying to increase the morning dose to 200 mg but I keep getting sick. (I was on it before for 2 months with no problems.) Friday morning I tried to increase it. I quickly and suddenly felt faint and dizzy and nauseous, and then I threw up and then felt better. I skipped Friday night and Saturday morning and then took my usual 100 mg Saturday night. Within 5 minutes, I felt strange in the head again and my heart was racing. It finally went away, but now I am afraid to take doxy again. What is this? A side effect or a reaction?
Part 2 -- POTS question. I have been suddenly feeling dizzy and feeling like I could pass out randomly while standing or sitting. I'm OK when I get up, and it will hit me some random amount of time later. Sometimes it's just dizziness and it goes away. I've had my blood pressure taken while laying down, sitting, and standing up several times recently and nobody said anything was off. Is it possible for your body to adjust OK at first but then misfire later?
