It's been a very long time since I've posted, but your situation was very similiar to ours. Brief background; my daughter now 10, was on 2.5mg of abilify for 1 year. She was also taking Strattera as well for a bout 2 1/2 years. I too, at the beginning thought the abilify was working so well, until, 9months later during spring, she had her usual terrible breakout of her tics. They were so bad that she was self torturing herself and couldn't stop. This was why we initial took the abilify and thought it had stopped it. It appeared that for some reason, this bout seemed to be seasonal. Every spring for the past 4 years this has happend. Before taking the abilify I researched holistic approaches but with mixed results, so it was just the next step to try meds. After this last springs' bout, I chose to chuck the meds and see a DAN doctor-we had nothing to lose. He saw her at her worst. My insurance covered 60/40, so at least I had some coverage. On our first visit, he recommended that we try a gluten free, dairy free, sugar free diet, until the test results came back and showed what foods she had a high reaction for. One month later, the tests showed she had reactions to milk, eggs; white and yellow parts, yogurt, sesame seeds. Did I see a change during the first month? Yes, but I could not honestly say it was because of the diet, since her spring attacks last for about a month or so, and I told the doctor that. After the second visit, and taking the additional supplements he recommended, I noticed a difference in what I call her normal tic stage. This to me was HUGE! Its been 5 months now and her tics are still less severe than her average.
The DAN doctor made such a difference than me doing it on my own because of the testing and knowing what she was deficient in. This in the long run saved not only money but TIME! He also made himself available via the phone for questions or changes in dosage/supplements. She is on 4 different supplements that have really changed her life. How will she do this spring? Your guess is as good as mine, but if her normal tics are any indication, I think we will be better off this time around.......god help us if I'm wrong.
My advice is to do what ever you have to, and go to the DAN doctor as soon as you can. Remember results will not happen over night but at least you will have started the ball rolling.
