"i&#039;m 20 and have had acne since i was 13. i only started on this a week ago with the 50 x twice a day. but the first 3 days i missed at least 4 of the tablets. this has caused me to majorly breakout worse than before i started. i&#039;ve had to drink lots of water because i have been getting bad headaches (nearly migraines). i havent had problems with dizziness or infections. its probably too early to be posting but hope it helps."
