"i&#039;ve been on effexor xr before and was off it  for a few years. life got tough again and new dr put me on 10 mg lexapro. after a week, i can see light at the end of the tunnel and it might not be a freight train! after months of not being able to get back to sleep when i wake in the middle of the night,  i&#039;m now sleeping much better. fuzzy thinking and digestive upset for a few days.  i don&#039;t have much of an appetite, but that is really a good thing! i feel a little more focused too. i can feel my mental energy returning. so far so good."
