So I was taking lexapro 25mg and I started waking up at 5-6am with anxiety and shakiness every morning. My dr said to back down to 20mg and see what happens as 25mg might be to much. So I went down to 20mg and started to feel better less shakiness and after a while was no longer waking up with anxiety and could sleep in and take naps again. Fast forward 5 months and I am now going thru the same thing again. Anxiety waking me up at 5-6 am with anxiety lasting throughout the day until the evening time. I hVe had to take more xanax than I like to. So last night I split my lexapro and took only 15mg. Still woke up with anxiety but it seems to be not as bad today. Why would this happen. Normally if u have breakthrough anxiety you would up your dose not lower it. I have been on lexapro 15 years on and off and never had this issue.Anybody ever heard of this before?
