My psych doc told me that Olanzapine (Zyprexa) is a sedative, and that Lexapro can counteract Olanzapine's sedative effect. This is why he recommended that I take the Lexapro earlier in the day, preferably in the morning if I can.
Yesterday, I had taken my Lexapro about three hours earlier than usual. And today, I actually got out of bed about three hours earlier than usual. This is definitely a plus. And I then took my Lexapro shortly after getting out of bed. I am going to try to get out of bed a half-hour earlier than I did today, tomorrow. It appears I am on the right track, so far.
I appreciate your replies, Yaowen and cool09.
