Patient discussion about withdrawal

Q. ALCOHOL WITHDRAWAL what are the symtoms of it?

A. thank you dagmar--i hope this answer will help people to understand what this drug can do to you---peace---mrfoot56

Q. I may be healthier now, but miserable… I’ve not been smoking for a whole month (my longest period in the last decade), and I do feel a bit better physically, but it seems that I lost the joy of life – I don’t go out with my friends any more (because they’re all smokers), I envy other smokers, and generally I feel nervous and dull. Will it be like that forever or is there hope?

A. Well, try to think about what are you missing? The foul smell? The yellow teeth? The feeling of suffocating next morning? Whenever you feel longing to cigarettes, try to think again why you stopped smoking- and it’d help you to keep with it.
