The problem with NAC is it causes nightmares in some people. Is it OK to take it in the morning rather than before going to bed? By the way it's worth mentioning NAC is the same exact substance like in the ACC cough pills but can be bought in bulk powder 10 times cheaper. Many people take it (as an extremely potent antioxidant) regularly but it's not clear if prolonged supplementation can prevent cancer or cause it.
