My husband and I just started our first cycle of clen (we are on the two weeks on) and I am feeling really tired and headaches are horrible. I am only taking one pill in the morning and one in the afternoon. Will these sides go away in a few days? Also, what should you avoid taking while on clen (any specific meds, alcohol, etc?). I have searched for an answer to that one and haven't seen one. Any info would be appreciated. Thanks!
