that alprazolam does make one tired. Even after being on it for years it still effects me that way....tho' certainly much less so than in the beginnning. And I have to take my anti-d at night too as it also contributes to feeling fatigued. I don't know what that first med you are taking is. I will have to look it up.
You are very conscientous, so I am sure you will get it worked out.
