Suboxone usually does what other opiates do-- it doesn't so much as put weight on as prevent weight loss. When i was using and then in detox I lost 30 pounds from being sick all the time; my appetite didn't come back for weeks and weeks. So the Suboxone might just be restoring your normal appetite-- and the weight loss while off them was the effects of no appetite from opiate withdrawal.
As for the 'just screw it' comment, and as a psychiatrist, I urge you to take a good look at that thought, because those sorts of thoughts are what lead to people destroying themselves. The way to lose weight is to exercise and eat less and eat more healthy; those things would be a better idea than simply relapsing or putting yourself in a dangerous position.
Even if Suboxone was causing the weight gain, I consider it to be pretty small side effects for a treatment for a fatal illness. Compared to chemo, Suboxone is a good deal.
Thank you for your reply. I have one last question. you metioned that opiates prevent weight loss. So with that thought there as long as I am on the suboxone I wont be able to lose the weight even on a strict diet and excercise routine? Or is it still possible to lose the weight maybe just at a slower rate?
Thanks again for your info. I find myself getting really depressed with the weight gain.
