You're not alone. I've been very depressed with not smoking. I've heard that it can take a year for the "happy" chemicals in your brain to straighten out. Ugh! I've tried a couple of anti-depressants, but have bad side-effects, so am only taking neurontin now to help anxiety, and lorazepam. When does the craving ever go away? This is soooooooooooooo hard!
