Tramadol is an interesting compound, especially its major metabolite (+)-O-Desmethyltramadol. It is really useful to taper off short and long acting opioids with this medication. If you develop a month long hydrocodone habit....in excess of ~50mg per day....switching to tramadol for a week and doing a short taper can really help.
I actually had some very interesting CEVs on ~15mg of DMT crystals w/ the GVG combined with tramadol (100mg). I was also on 30mg of morphine sulphate. I wasn't trying to get that high with the opioids btw...I just seriously hurt myself about a month ago and pinched a nerve. Nothing permanent but it hurt really bad.
