Hi. I m a recovering meth addict and have been clean from all drugs for 18 months. I used meth over a long 10 year period and used it in every way possible from IV to rectally. My favorite way to use it though was to wrap it in tissue and swallow it. I usually would swallow between 1 and 3 grams at a time and would often become violently ill. Currently Im expieriencing stomach pains and nausea after anytime I eat. How after 18 months of being clean can a problem arise. My dr. Knows im in recovery and has prescribed me promethazine for the nausea. In addition I had fissure surgery 7 years ago and am also currently experience embarassing anal leakage. Any ideas as to what i. should be telling my dr. and what could be going on with me.On a side note i havent ecpierenced any weight loss and have gained over 100 lbs since i have gotten clean. Im 5ft 11in and went from 150 to 280 lbs.
