Whats happenin bruv, can dig were your comin from there. i was at college in exeter and spent 2 years smokin it up all day long with hash shotties and hash bongs.

Initially the high was an all round body high but once that wore off(after about 1 year), then the pshycological effects started for a lot of my peers down at college, causing paranoia, avoidance of people, anxiety and general feeling of depresson. I myself only found that whilst sober i would be more lively but thinking about weed a lot and actually getting excited about getting a smoke on. THEN after all of that good feel vibe, i would have a bowl or two and would then wish i hadn't smoked.

Weed is all about effects of the mind, in time these feelings will disappear although apparently there will always be that slight feeling of anxiety. To be honest your probs best giving it up ("if you want to extinguish a fire, dont pour more petrol on").
Good Health bruv, LOOK AFTER YOURSELF and dont you go thinking too much.
