"anxiety lifer here. my demon has gotten cruel in the past few years by manifesting itself in severe premature ventricular contraction (pvc&#039;s) every time i start to leave the house or get in a slightly stressful situation.  after a massive panic attack on a flight home from london to dc, i decided i had enough. i told my gp i want to go back on lexapro. like every other time, lexapro works almost immediately for me - my pvc&#039;s and agoraphobia have muted drastically on only 5mg a day! yes there is slight weight gain and potential sexual side effects but i&#039;ll take those over the other stuff any day. it&#039;s cliche but i do feel like i have my life back. i even ventured out for a run around the city tonight with zero pvc&#039;s. sucks being on a drug but i&#039;m ok with it today."
