insomnia
"I started this medication (7.5 mg) to treat insomnia that my psychiatrist thought was due to underlying anxiety disorder.  Like others, I felt very dopey and groggy out the first 4-5 days.  Have now been on the medication for 2 weeks and this has abated, but still with lower energy level during daytime.  I have found that a Claritin-D in the AM reverses this feeling as well as reversing the increased appetite.  Insomnia is improved - still a few days with difficulty falling asleep, but once I'm asleep I'm out until my alarm goes off."
