I just started lexapro but I haven't experienced anything yet besides upset stomach so I'm taking half the dosage for the first few days just get used to it. This may be in my head but a couple of times I think I felt more down than I should have, but only for like 15 minutes. I was on paxil in my younger days (for anxiety, not stuttering) and my mom thinks it helped me and encouraged me to go back on. I honestly don't remember if it helped my stutter but it absolutely helped with anxiety.
