It’s not a good idea at all :( I know it’s very tempting if they are making you feel worse and you just want the pain from them to stop and I have a bad habit of doing that myself, but it will be so much worse if you stop them all at once. I should know, I was on all of the medications you listed at once plus a few different ones and I stopped completely one day. It was the worst pain I’d ever felt in my life and I legitimately thought I was gonna die, I couldn’t even stand up. I had to go to the hospital and get an iv and even after I was discharged it took me weeks to feel somewhat normal. It was so painful and I really don’t recommend it :(
