I had the same experience. It got so bad I had to get off this antibiotic completely. I switched to Doxycycline, I have not had any negative side effects on doxy. Mino made me feel terrible all the time. I usually tolerate meds really well too. talk to your doctor if this continues.

Im on minocycline and have been for 2 weeks and sometimes I feel dizzy, or feel sick to my stomach but I learned that with the more water I take with the pill the better I feel. Hope this helps!
