This is a known fact that ultram can do that to certain people. I have not heard of many people having this, but have heard it before with high doses. how many pills did you pop that day? did you take a lot of them? I am surprised you got a buzz off them as most people feel nothing but a small amount of pain relief, they don't give you the europhoric feeling opiates give you but they do help a lot with W/D'S. I have ran out of meds before and have used them and they made it so my W/D'S went all the way away.
It is also an addicting medication and is many, many people end up being addicted to those after they have come off vicadin. its more common than you may think.
That is so scary about your seizure. I am glad your okay now, and thanks for the warning...
i hope your doing well and staying clean!
