Getting Perscription Drugs in Monterray

I have no insurance and currently take about 5 blood pressure pills per day and a cholesterol lowering one as well ) Advicor) and Ambien. I live in florida and am not able--under FLorida law --to oreder perscriptions from Canada. So I am paying abo9ut $500 per month out of my own pocket :*( I plan on lap band surgery in Monterray in JUanuary.. ( to be confirmed Friday with Dr. R's office). Does anyone know if I can purchase my blood pressure meds down there--since I am sure it MUST be much less expensive than what I'm paying here in FLorida already? Please email me or respond on line. Thank you all for your help, warmth and the ability to give good info to help us all out. I've talked and emailed with several people since I found this site last month and just been KNOCKED OUT with how wonderful most folks here are. Hugs to all! Gail
