I take Tramadol too.. 50 mgs (1) every 6 hours or as needed. I talked to my dr. last week about just this subject. He said I could take as many as 4x a day so, that would be 200mgs a day, at least for me. I'm sure alot of it has to do with your size and weight. (I'm no lightweight, about 40 lbs overweight ) If you're not 100% sure what's right for you.. call your Dr. - they'd rather you call and ask and take your meds properly than just guess. And if you're in extreme pain, you should let them know that, too.
Hope that helps.
