I went to my doctor about two days ago and she said I have to take Doxycycline tablets for a month i believe but I'm not so sure. I have cystic acne and I'm on my second week of using the Regimen. It's sorta helping. Today is my first day of using the tablets and I've been looking at the reviews and there are some odd side effects and strict rules. Can you guys tell me how'd it go with you (if you tried it)? I'm fifteen, by the way. THANK YOU SO MUCH! 
Ps: Is it okay if I try it with the regimen?
I was prescribed with doxy along with clindamycin for my acne 2 years ago. I stopped taking antibiotics after 3 month or so after hearing how in the long run antibiotics will make things worse for your body. In the 3 month I haven't really seen any changes, maybe minor. I decided to take left over doxy again when my acne got bad in college but now it just makes my stomach upset so I just gave up on it.
