My son has been on every med possible over the years (or it seems to me) He has been on dexedrine, ritalin, haldol, prozac, anafranil, zyprexa, etc. All have side effects, especially zyprexa with the incredible weight gain and compulsive eating. We finally decided to take him off everything. Recently, we tried the supplement l-carnosine and feel that it has helped him more than any medication ever did. We have also tried biofeedback, dmg, fish oil etc. over the years to no avail. I know l-carnosine doesn't help everyone, but when it does, it is really exciting. If you have not tried this, I urge you to look into it. I also agree with the sensory integration issues being looked into. Good luck!
