My roommate tells me that i toss and turn very much while iam asleep? checked by entering doc and he dismissed sleep apnea what may cause this

Not so fast, here: You could still have a sleep disorder, and this could include "paroxysmal limb movements in sleep". and a "REM sleep disorder", but sometimes, sleep apnea appears in this guise. If you have sleeping problems, an overnight sleep study could be very revealing. Maybe you need a second opinion.

Second opinion: was your doctor qualified enough to dismiss it? often times this could be sleep apnea or related to some other sleep disorder. if you are not satisfied with the response, perhaps you should consider an evaluation by a sleep specialist.
