You may not feel the effects now but I guarantee you will. 10-15 drinks is a lot. Things are happening to your body that you do not realize. Despite popular belief, you can have withdraws several days after quitting. I cared for a woman who under went surgery on her hip. 5 days after her surgery, she started having severe withdraws. Extremely high blood pressure, hallucinations, tremors, sweating, seizures. Her husband told us he was surprised it didn't happen sooner as she drank a big bottle of wine every night for years. If you are unsure if you have a problem, try quitting for 90 days. I would however speak to your physician before doing so. Good luck
