"i did not enjoy being on tetracycline. i got extremely nauseous and almost vomited several times. it was a lot to put up with for little results. it also took a while before seeing results. i also noticed i was bruising a lot easier. i switched to minocycline which i like a lot better, i noticed better results and i have no side effects! if you&#039;re having the same problem as i did with the side effects, switching to minocycline (the sister of tetracycline) may be beneficial for you! goodluck! i know acne can be super stressful but don&#039;t let it get you down, it never looks as bad as you think"
