"i have been on lexapro for generalized anxiety. i started 5mg for 4 wks, just upped it to 10 mg one wk ago.  for the first week i had slight headaches, sweaty palms and hot flashes.  when i went on 10mg i had a little increase in anxiety and trouble staying asleep, but hopefully this passes.   i felt my anxiety decrease the first couple days on it, but the feeling of &quot;dread&quot;  is just starting to decrease after 4 weeks.  overall i this medicine is great and i helping me function and live a normal life."
