Hello, I'm 23, smoke cig's and weed - about 20 cigs/day and about a gram a day of weed. I haven't smoked a joint since Saturday night, I'm a heavy user 4-8 spliffs a day, say .25 grams per joint during the week and then anywhere between 1/8 oz and 1/4 oz on the weekends. I haven't been without weed since about september last year, during that time I had the same problem as what I'm about to describe. Last night (Monday night) I was getting hold and cold flashes, sweating and felt very nauseated. Every time I laid down to go to sleep I would get so hot that I would have to go outside and cool down. Strange, but when I was sitting up I wasn't getting as hot. A couple of times I got really hot, sweated quite a lot and then was very very cold. I went for an hour long walk at 6am because I couldn't sleep, I got back and I was still getting the hot and cold flashes and wasn't able to sleep. I was feeling nausea and eventually was sick. I eventually passed out rather than went to sleep at around 8am or 9am. I'm still getting the hot flashes as I type this message. Last time this happend it passed in a few days. Now I'm seriously wanting to give all this up, but I don't feel like I have the power too. I wonder if anyone else has had any experiences like mine. A mate of mine who I smoke with on a regular basis says he hasn't had this happen to him, but he doesn't smoke as much as I do during the week, he does at the weekends. I went to my doctor, but he didn't seem to care or be able to speak very good english so thats pretty much a dead-end. I've read about a few symptoms of withdrawal from cannabis and a lot of other stuff saying there isn't any withdrawal symptoms associated with cannabis. I'm wondering whether this is a way for my body to "flush out" the toxins that it couldn't do while I kept topping up my THC. I've read that other drugs cause these types of symptoms. I've also been getting quite bad chest pains for about 6 months - all this should make me want to stop, but it doesn't - I don't feel like I have control. Does anyone else share these experiences or have any advice, I feel lost and I don't know what to do. Thanks.
