Hi, I was just diagnosed with tonsillitis the other day by my doctor and he prescribed me Abbocillin 500mg to take 4 times a day. For the first afternoon he wanted me to take 2 at a time, so that day i took 6, two at a time, at like 5, 9 and then when I woke up at 2. Then today I had 1 at 7, 1 at 11 and one at 3, but I'm starting to feel so sick. My stomach feels very bloated and uncomfortable and when I tried to eat lunch despite feeling very hungry my stomach was not happy to have the food. Now at almost 5pm, I still incredibly bloated and very uncomfortable. Is this a normal side-effect of taking antibiotics or am I possibly allergic to it?
