Welcome to the forum! Tramadol is a totally synthetic opioid and also has an antidepressant component in it so can be more difficult in some ways to w/draw from but can absolutely be done! I read in your other post that you get these pills online...which also means you aren't guaranteed what's actually in them, ya know?
Using Kratom is probably not a good idea....it, too, affects opiate receptors and isn't "controlled" so you don't actually know what you are getting from your supplier. It can be addictive, too....so forumulating a plan to get off the trams is probably your best bet. (your stomach issues will get better for sure once you get off them, too) Some forum members here have cold turkeyed off Trams....other's have not. Some had seizures while ON the Trams...others have not. There is a seizure risk depending on YOU so that is why others recommend tapering. But....if you're like me, tapering didn't ever work. If I had pills in my possession....I went into panic mode and just took more and more....when I fully intended to taper.
It would, of course, be best to get your dr involved for utmost safety, but if you have been there..done that...and get your pills online, I understand why you don't want to do that. Just know that would be SAFEST for you.
There is a wonderful group of Tramadol Warriors that talk amongst themselves about the particulars specific to Tramadol addiction and w/drawal. They have been doing this since Emily Post started a journal way back in 2008. (bless her big heart!) They are actually on Journal #61 now. I'm thinking it would bless you A LOT to read those journals....so here's the link for their most current journal:

I wish you well on your journey to freedom~
