i found pot helped with the body feelings and nausea. i wouldn't reccomend putting yourself through more than you have to, IF you're already dependent on anything else (physical or psychological). if you have no other dependencies then by all means go clean, though you should really look into immodium AD for your gut
good luck. i don't think it's a matter of being strong as much as realizing it'll get better and having hope. at least for me. sorta a waiting game
