I am wondering if anyone else has been suffering with extreme fatigue from lexapro. I've been taking it for a few years, but I recently got fed up with the constant yawning/tiredness. (Does anyone know why yawning occurs as a side effect?) I tried taking it at night, but got reflux, so I take it in the morning. I wondering if I should try taking it at night again, or if that will make a difference in terms of decreasing fatigue? I recently tried cutting back from 10 mg to 5 mg and noticed a significant increase in my energy level. However, the 10 mg dose was more effective.
