Moose isnt your long naps during the day playing into this kinda of chronic inability to sleep over all at night???? I know you are wanting to cut your Seroquil out and that opens a can of worms of needing to instead do a slow taper off of or yes Insomnia is going bite you in the back side..

What prompts your napping daily? Do you just get so tired you can not keep your eyes open? or do you sleep when you are watching tv or reading something? If you are in bed and comfy then yes a nap is likely to happen, So maybe get up in the am and make your bed and do not go back to it???? You can read of watch TV in your living room instead.

I honesty think you would benefit greatly if you stopped any and all napping and do a slow taper off Seroquil..

Just a thought
