Got a prescription to viagra and really want to realize the benefits and not add more anxiety to the experience. Normal evening routine would include dinner and a couple of glasses of wine (beginning at 8 or 9pm) --home and ready for action at about midnite. Should I immediately go with the 100 mg. dose and would it be best to take it before dinner or after? I understand alcohol can diminish the effects - how much wine is too much? Thanks
