Escitalopram
"I started using this medication for GAD and for depression. I started off with 5mg for two weeks and gradually worked my way up to 20mg. The first week of side effects was terrible: insomnia, nausea, mood swings, upset stomach. But I continued taking it as recommended. I used it for about six months and saw no positive changes. I experienced many suicidal thoughts, strange dreams, sleepless nights, sleeping too much, and crazy mood swings. This almost caused my boyfriend and I to break up. I would not recommend it, but it may work for someone else. I am on an SSNRI (different family: Effexor) now and have no side effects."
