I wonder what has been making me so exhausted that I sleep most of the day and night, several of my medications can cause drowsiness. Here's everything I'm on:

Allergy Meds:
Singulair 10mg
Zyrtec 20mg

Psych Meds:
Invega Sustenna 117mg
Depakote 750mg
Paxil 40mg
Hydroxyzine 50mg x 3

I'm also prescribed Trazodone which I haven't had to take lately because of this. Is it a specific med I'm on or a combination of them? What can be done about it?

I'm going to cross post this in the Psychiatric Medications forum
