^Hell no dude, don't mix all those pills like that. Besides being bad for your vital organs (esp. liver), doing that can cause seizures. After you get one seizure, you are now way more likely to have more. Also, you could choke on your puke. Mixing pills probably won't kill you right away, especially if in moderation, but its just plain bad for you. Tramadol + another opiate/opiod + alcohol will give you a seizure in a heartbeat, happened to my buddy. Scary stuff, man.
Soma and benzos could lead to passing out, hope you don't have respiratory problems like sleep apnea, you could stop breathing. Or (once again) choke on your throw-up.
I mean you probly aint gonna listen to some dude over the internet anyways. I am a nursing student, though, and I speak the truth. Do a search right here on BL, like "bad pill combinations," and you can find some damn good info.
