Tramadol
"Stay away from this drug. Few Doctors know how intense it is and what its effects are.  I was precribed much "stronger" opiates before and after, up to oxycodone. Tramadol blew them out of the water. 



I have (had as of 1month ago) been on tramadol for 7 years.  I have 2 pars fractures in my low back and this was what I relied on to alleviate any pain. I started with a single 50mg/daily and gradually worked up to 400/mg. I never abused the drug, I simply did what the doctor told me to do. 



The level of addiction and dependence to this drug is insane. The withdrawal is the worst thing I have ever experienced. Because of that and its negative effects on my life, relationships, work and happiness, I checked into a detox program and am done."
