There has been talk of how much tramadol is to much and the effects on the liver. My average is 150-200mg per day and really helps with the burning.
My thoughts are no point spending years in Pain and checking out with a pink super healthy liver, you cant use it when your gone!
As a matter of interest check out this tramadol abuse forum. keep in mind a vast number abusers are middle class . some of the doses are scary
