I'm on 10mg of lexapro daily and it's done wonders to silence the intrusive thoughts for me.  I missed a dose one day and noticed I was very tired the next, which was one of the side effects I noticed when I started treatment. Is missing a dose a big deal? Also I'm wondering if it's ok to have a drink while taking the medication.  I never get drunk but like to have one or two when I'm out.  Anyone have experience with this or similar drugs?
