hi. I smoked meth, cigarettes, and weed for 7 years. I quit all 7 months ago because I couldn t breathe and was going numb, and heating up, and one time my eyes started rolling back into my head and I nearly fainted. Anyways, I used to be able to do almost anything physically, now I have good days and bad days. I can t really over exert myself to do anything, and even though now I eat 3 meals a day, take vitamins, and drink a lot of water daily, I still have these unusual episodes. My ears clog up, my jaw tightens up (right around the cheek-bone or temple), and I almost black out and faint. My only strategy to counter this is by holding water in my mouth. Please, my question is: what is going on with me? Has all the smoking I ve done made something collapse in my brain?
