HYPERSOMNIA

My dx from my pdoc is depression and anxiety. I take citalopram, diazepam, and adderall. All doses in a.m. My issue is that if I don't have to be up for work or an appointment, I sleep 12 hours per night. I could easily sleep more but as it is, I feel like such a bum waking up at noon. The night before, I have good intentions of waking up at a reasonable hour where I set alarm for 8 hrs of sleep.
So mon thru thurs, I am sleeping 12 hours. I work evenings during the week and days Fri, Sat, Sun (up at 4am).
And just to clarify, I have had this problem even before ever starting meds.
Is there anyone else out there with this problem? If so, have you found any solutions? Any insight would be much appreciated as my depression is getting worse since I get down on myself for sleeping the day away and being non productive.

I used to have this problem a lot, I'd have a combination of insomnia, staying up until 4, 5, 6 in the morning. Then sleeping for 12-14 hours. I know it sounds like the advice they give all the time, but really getting on a schedule has helped me phenomenally.
Now I sleep from about 9-10 pm to 8-9 am. Which, while still a long time, makes me feel like less of a bum as you put it. One thing I've found to be an absolute miracle is zzzquill, which is liquid diphenhydramine (benedryl) with a little alcohol. It doesn't react with my meds and can put me to sleep within an hour most nights.
Hope this helps, -Alec
