Why exactly? Is there anything I should be concerned beside weight gain?
You are 17! You don’t need pharmaceutical drugs! Have you read the list of adverse side effects? Horrible.
Eat a decent diet, exercise, get plenty of sleep and sunshine, avoid alcohol/tobacco/drugs/stress and you will be fine!
Don’t go crazy on the supplements either. I’ve done this personally and it only caused more problems.
Some posters here give the impression that the only way to heal is to take massive doses of drugs and supplements while eating an extremely restrictive diet. This is not true, so don’t fall for it.
