I was on tramadol for at least 10 years----100 mg. then my doc took me off because a neurologist put me on Clonazepam for REM/SBD (rapid eye movement sleep behavior disorder.) But I was also getting cervical and lumbar rhizotomies...and still do every 12-14 months or so. I am now working with the VA for a pain med that will not conflict wiith clonazepam. Back to tramadol....taken off because of the interaction etween the two. The tramadol was kind of a maintainer/sustainer inbetween the rhizotomies. it worked well for me. I would go back on it if they let me....but they wont. Not much to add to that. Its not addictive. MGs vary on the usual variables---other meds, weight, and so on. Good luck.
