Dear pandora1975
Welcome to HealingWell and the A & P Forum. I am wondering if your having some anticipatory anxiety worrying about how things are going to go wrong when you go out.
May I suggest that you just do not plan on drinking any alcoholic beverages and stick to soda, water or even a virgin frozen drink. No alcohol worries may drop your anxiety to pratcially nil. No worries about upset stomach.
Please do not let your peers talk you into alcohol if you feel it is causing you problems.
Take care and keep posting. We are delighted to have you here.
