I just tried Tramadol for the first time two nights ago....I have to say, the high was pretty nice, I combined it with some bud....however, I got the WORST nausea from it, which lasted through until the next day and made me leave work early.....now the nausea could have been from any number of things, but I'm leaning towards the Tramadol because it began to hit me about an hour or two after ingestion. I am going to try Tramadol again to see if the nausea is directly related....if it is, the high Tramadol gives you is nowhere near woth the nausea you (or at least I) have to suffer.
