Regular tramadol wakes me up too. I take it only 8AM, noon, 4 PM. It only lasts about
4 hours for me. At 8PM I take an estended release tramadol (also cheap generic). It doesn't work nearly the same or as well as the regular one, but lasts about
twice as long and doesn't give me insmnia.
I can't take tramadol even the same day as any muscle relaxant or much of anything else. Taking the same day as Flexeril gives me immediate serotonin syndrome.
