Hi there, I have a strange question that i cant find the answer for. I took Tramadol/Zydol for around 7 months for back pain, ever since i stopped taking it i cannot get the effects of alcohol e.g the buzz, euphoria. please note it is NOT a tolerance issue, i can drink and drink until im sick and not feel anything. (it was just to test how much i could drink/prove it wasnt tolerance) i have been in abstinence from Tramadol for about a year now, im really worried im permanently damaged. any help or ideas why this is happening? thank you
