Tramadol
"I've been on tramadol 50 my 3x day for 7 years now for arthritis. It's a very good pain relief it also helps sleep good an helps with my anxiety issues. But my tolerance level started to get high after a year of taking it. It stop working good so I had to start taking four a day, then ended up finding out I'm having withdrawal symptoms which is VERY TERRIBLE thing to go through. I suggest if anyone taking this... *WARNING* if u feel like it not working anymore and you've been taking it for a long period of time stop taking them that means your getting addicted. Or just take a break from taking them for a bit. Went through hell with the withdrawal from those."
