I tried pot at a teen and hated it. I am now in my forties, have VSG 2 years ago. I started having horrible shoulder pain about 6 months in. Turn out I have terrible arthritis and will need a should replacement. My pain control options are narcotics, nsaids, or pot. Narcotics come with a whole load of problems. Nsaids are a no-no with bariatric surgery, however doc gave me a pass to allow me to take. And pot works the very best. However it does make me very hungry. I did not re-gain do to pot, but I do not continue to lose when I am using it. When the pain is bad, I use pot each evening. I am not able to sleep without it due to the pain.
I would say stay away from it. If makes it possible to eat much larger portions than without it. It seems like I do never get very full after a full portion.
STAY AWAY!!! No use going through all the trouble of the surgery to throw it away with the side effects of marajuana. For me, I will continue to use till I have my replacement surgery which should be later this year,
