First let me congratulate you on your decision to stop drinking. I did that January 2001 and haven't looked back once. I am a recovering alcoholic.

Second, it is perfectly normal during the first two weeks of induction to feel fatigued, weak, muscle soreness, feeling like you are going to fall flat on your face. Been there done that.

Are you taking any kind of supplements and vitamins? You didn't say. Taking magnesium, potassium and calicium will help with the muscle fatigue and the tired feelings.

As for the rash, are you eating something new that you haven't before? Could it be the vitamins/supplements if you are taking them? Sometimes the binders they put in those can cause a reaction. I know I personally can not take some brands of vitamins because of the binders. They make me belch all day and the feeling of nausia. The rash sounds like a food allergy or possible medication reaction.
