Betosca, I'm glad you posted this question because it is something I wondered about. It was suggested that I start taking Ativan, but like you I knew I'd have a really hard time knowing when to take it. I knew I'd constantly 2nd quess myself about whether I was "anxious enough".

So at my most recent pdoc appointment I talked about this with her. I told her I wanted an anti-anxiety med to go with Lexapro, but didn't want to have to make the day to day decision whether to take it. She said I could take .5mg of ativan twice a day. I didn't have to make a decision on which day to take it. So that's what I've been doing. Maybe you could try this as well (check with pdoc of course). See if you can take it twice a day at the times you typically become most anxious for a couple weeks and see if that helps at all.

Personally, I'm trying out 9am (after I get to work) and then again in the mid-afternoon.
