Not sure if its Hyclate or not, but I am taking Doxycycline for an eye infection (100mg 2x/day). At first everything was ok, then after about 4 days, I stated having some nausea and acid reflux (throat seemed to be burning). I have to take it for 3 more weeks, but next week only 100mg/day which I hope will help.\
Is this typical of an antibiotic that you might not get any side effects until it build up in your system?
