Sleep or Happiness - which would you choose?

So Ashley has done so well on the enzymes and we are so excited about the changes in almost every area of her life - except one - she still doesn't sleep. After another trip to the doctor, we decided to try a new medicine, an anti-depressant that helps with sleep. Now we know we have to start with tiny doses and work our way up or Ashley will react. So the first night we gave her 1/4 of the dose and everything was great. She went to sleep easily and stayed asleep. The next two nights it made her hyper. So I called the doctor and we decided to push to the actual full dose. Now her sleep is much better, however every other night she gets up at 5:00 in the morning. Now I know my dad would have considered that a good wake up time, but I consider it the middle of the night. And to top it all off she is highly cranky a lot of the day and very aggressive at school this past week. Am I really going to have to choose between sleep and happiness for my child??? I have another call into the doctor, hopefully he is prepared with a great plan!
