I'm A 51 Year Old White Female. Currently Taking Celexa

I'm a 51 year old white female. Currently taking Celexa 20 mg 1x per day, wellbutrin 100 mg 2 x per day and xananx 1 mg at bedtime. I'm being treated for grief/depression. Ex smoker for 17 years, began again 1 year ago (1/2 pack per day). drink beer 3-4 times per week (5-6 beers). I've had nausea/no vomiting for approx. 1-2 weeks. The only time I don't feel nauseous is just after a meal, then it comes right back. THERE IS 0% CHANCE IM PREGNANT.
