I have been having this problem for a long time. I even ended up in the hospital because of it. I take Focalin which is a stimulant and once I take and get out of bed within 30 minutes I am awake and not taking any naps during the day anymore. I am allowed to take two a day but I am finding out that one gets me through most of the day but I want to go to be around 8 which is actually not a bad thing.
