Hey good luck man... I dont know if you are a Mt dew drinker or not. But, Side effect #1 is going to be a headache. NO CAFFINE would render me useless for two to three days until my body got past itself. Would be like someone stopping crack cold turkey, for me anyway. I get migranes like a mother now, so Mt dew and tylenol are always with me. Have to wear perscription sunglasses and be leary around the water because of all the reflecting. It's rough.
