I Have A Serious Question With Serious Concerns About My

I have a serious question with serious concerns about my med combo. Can I take my Adderall in the morning, then later at night take my hydroxyzine and Lexapro at the same time? I have a tolerance to my Adderall so it doesn't really mess with my sleep, though I have never been really able to sleep. I was put on hydroxyzine for my anxiety and inability to sleep properly. Now that I have been prescribed Lexapro I haven't taken my hydroxyzine at night with it yet. I have only been on Lexapro for 2 days now. Taking the Lexapro last night I was expecting it to help me fall asleep but it did the complete opposite. It left me restless, uncomfortable and more unable to sleep than usual. I was up until 6am trying to fall asleep. I took my Lexapro at around 11pm and it is now almost 3:30 am. I need to know if I can take both Lexapro and hydroxyzine together, at the same time at night.
