I found lower dose did not control pain which is 8-9, difficulty walking/moving. 75 was effective but trouble staying awake. Does drowsiness lessen? I noticed that in the morning my hands, feet, legs were very swollen, which has never happened. It would lessen during the day - stopped med 2 weeks ago - still some swelling - could this be side effect in lieu of sweating? Had blood/urine test - all normal
