hi, i have stopped smoking weed for 7 days now. i smoked heavily every day and stopped outright. i have done this before, with only the usual problems, lack of sleep, excess sweating, vivid dreams ect, but this time im getting heart flutters (not so much palputations) that leave me short of breath for a short (few seconds) period and is very worrying. im 6 ft 2, 10 1/2 stone, take nasal spray, im 26, been smoking for 10 years with a 1 1/2 year break, still smoke cigarettes, have recently started to take a berocca a day to suplement my not so great diet.
