Suddenly UNWELL on tramadol

24f, on no other medications. Diagnosed with endometriosis and chronic pelvic pain.

I’ve taken tramadol off and on for 6 years (I don’t take much anymore but on occasion), anyway I’ve never had an issue taking it until relatively recently.

i cannot sleep, the next day i will have a migraine for 12+ hours i get very bad nausea and sometimes vomiting and diarhhea (10+ hours AFTER taking it). it tales me atleast the entire next day to recover. o dont understand?
