Thanks guys, i've done abit more extensive research myself and have found a condition that sounds just like what wrong with me, its called CVSA (Cyclical Vomiting â??Syndromeâ??). And almost all of my problems match up to the diagnosis. But apparently its quite uncommon so the doctor may have easily missed it, will be sure to mention it to him next time.
Interestingly enough, a study on some heavy cannabis smokers in australia with CVSA found that cannabis although relieved their symptoms, it could also of contributed to the illness in the first place. Interesting huh?
If i've literally smoked myself into an illness (that can not be cured) then i am not happy. lol

Its early days anyway, but i think im on the right track with this.. all i know is i need to find a answer that doesnt involve me spending almost all of my money on cannabis and hash to keep me alive.

I've lost over a stone in 2 or 3 months, im pale, not eating, i have to find some answer to this...
