The longer you smoke, the harder it will be to quit. Glad you are seeing the doctor about your skin issue. Whether it is connected to smoking or not, I hope you quit smoking soon. You need to replace drinking with a positive behavior like running, knitting, dancing, playing guitar...Be open with the doctor about both alcohol and smoking. Chantix worked for my husband when he quit smoking but he also took up jogging to deal with cravings.
There is not a drug on Earth that can make life meaningful.
