ADHD
"I have been using Strattera for about 10 months and had great success for the first 9.  I felt great, very focused and able to get things done, and had no negative side effects except for a little bit of dry mouth for the first couple of weeks.  About a month ago I experienced a bout of depression until my doctor switched my prescription from 1 80mg pill a day to 2 40mg pills each day (once in the morning and once in the evening).  After the switch, I was back to feeling great until last week when I had another bout of depression.  This morning I took 5mg of Ritalin and snapped right out of my depressed mood.  My doctor has suggested stopping Strattera and using Ritalin instead to try to determine if Strattera is the cause."
