Very good information and addvice. I will just throw in my 2cents. I agree fully with McGrath. I am having the devil's own time with nicotine, but I used Cocaine heavily in the early '80s and walked away without a problem. All people's chemistries are different,and if you are facing a challange God's speed, if you're asking "can I play here and walk away later" DON'T BE A FOOL..Mike
