Heat type symptoms and conditions

I'm on day 1.5, 500MG Biaxin. I've been prescribed this medication for Bronchitis and a sinus infection. I just took my 3rd pill and I feel just fine, I was having some heat type fever flashed just before taking the 3rd pill but it's gone away. I've had some pains in my stomach which turned out to be a my body getting rid of the infection....spent a few minutes on the toilet but seem to be better now. The taste in my mouth is very bad, I woke up in the middle of the night with a watering mouth as if i was going to throw up but seem to be good as of now. I'm feeling better thus far.
