"my psychologist originally suggested lexapro to treat my anxiety and panic disorder, then my doctor prescribed it. i was told that it is not habit forming and that it has low side effects and works well to treat panic disorder. i started out on 10mg for 3 weeks then went up to 20mg. my side effects have been mild and have included nausea (the first few days), weight loss (which i don&#039;t mind) because of decreased appetite, mild increased sweating, and recently trouble falling asleep. all in all i am very pleased with it and have had only one panic attack in over a month. i used to have multiple ones weekly. i feel like i am finally getting my life back and i would recommend this medicine to anyone."
