sounds pretty bad man, i think you maybe sensitive to really strong weed, alot of people are.... ive heard of people who have smoke week weed or hash evry day for years but they cant smoke skunk because its too much for them.....

you could have low blood pressure from the sounds of it, one of my mates fainted the other day because he was stones and had low blood pressure

you could have been experiancing the physical and mental effects of anxiety or paranoir, they can be quite bad: twitching, racing heart, sweating, irrational fear of bad things happening to you, strong dizzines, sometimes shaking, racing thoughts.

they are the 3 things i could think of, they may not be right, but im just tryin to help, cause ive had my fair share of bad illnesses from a long period of chemical abuse
