I have had MAV for 4 years and the last 2 years it lasts 24/7. I have been given various medications by consultant, and last week he gave me Gabapentin. I take 100mg at night and must increase by 100 mg each week. So far lightheadedness has not improved but I feel completely exhausted when I wake up. I just want to go back to bed. Does this medication help MAV and do the side effects diminish.
