sleepy, are you getting a cold or work. Some people just need more sleep, I know I do. 8 hours is right for me but I can imagine 12 is cutting into your day. Maybe it's time for a check-up w/a reg doc and a pdoc. It wouldn't hurt, there are alot more meds on the market for you to try. I'll keep you in my thoughts....good luck.......pj56.......xxoo
