There are natural alternatives. Are you open to that?

There is a sticky thread in Tourette's....

Read this first.

Then consider:
My experience is with ADHD and natural support. I have a thread on Vitamin forum on essential fatty acids and their usefulness in
many health areas, including the ADHD which we used them for.

This sticky has alot of concentrated information on the
most valuable nutrients:

For EFA support, and behavior support, B6 and magnesium are very important. They help metabolize the EFAs for the brain's use. EPA and DHA specifically are one type of Omega-3. The EPA portion has been studied in bipolar patients. If you suspect bipolar (the meds suggest that diagnosis), then EPA may be helpful. My son with the ADHD and anxiety diagnosis did better on high DHA containing fish oils. My son was able to stop his Ritalin after 5 yrs! and be drug free.

It seems overwhelming now, but start reading. When I started with this subject over 10 yrs ago, and Chemar also found me on the net, we were doing parallel things to help our sons.
Now with time, this approach has more medical support, and so it has been validated quite a bit compared to a decade ago.

Keep in mind that discontinuing any drugs now, would have to be done very slowly and carefully. In fact I kept my son on the Ritalin because we had no idea EFAs would work so well. He tapered of over a 3 month period.

So for now, just read and learn. Then you can PM me anytime or post here or at Tourette's (where Chemar watches) or at Vitamin forum (where I watch) and eventually you may find the answers you seek.

Hang in there.
