What about drinking some coffee? I offer this as advice, but I am not an expert, by any means. I know that, I have been prescribed valium, and I plan to quit tomorrow. I am worried about, errectile dysfunction too, so I am not going to use any nicotine ( at all). I am gonna chew gum and drink coffee, and take it rough I guess.
At night time, I m going to take a valium, to fall off to sleep. I hate to feel tired. It is the worst feeling in the world. Have you ever tried yoga? Or you could try a hot shower, to get your blood going.
Congradulations on your quiting. I hope that I am able to tomorrow.
