Sorry Half - but someone's pullin yer leg. =\ IMHO - there's nooooo way w/d's will take almost a week to come on. NO WAY. In some cases - like with Methadone use, I have seen/heard of them taking 2 or 3 days to come on - because of it being synthetic etc....but I'd hafta say there's NO WAY it would take almost a week. I see you said he did do some Meth - but sstill, if it were ONLY Meth, maybe 2-3 days tops.... I could be wrong here - that HAS happened every once in a while...lol....but I'm thinking you're getting the wool pulled over.....
Good luck to you friend.... Stick around and post - we're all here for you and will be here to help in any way possible.
