I stated in my first writing about the effects of quitting that I had learned about numbness and tingling in hands and feet was caused by the withdrawal. However, with memory being short right now, I don't recall where I got that info. Not sure if it was in this site or elsewhere. Wondering if anyone knows if it was specifically mentioned in this site? I haven't been able to see anything here specifically saying that it is one of the side effects. Help is always appreciated!
