I have been doing some research on other meds to discuss with his pdoc appt in may, so hopefully by then he can suggest something that will work as well or better without the weight gain, I did however find out today that he is doing great in school, especially math, which the doc friday told me he had brain damage in and reversed numbers remember me telling you guys that? anyways, They tell me he is doing fine, so I wonder if this testing we are all trusting in is just a result of his old schools' laziness. and they didnt want to help him in the first place, I tell you what, If I find out distinct differences between them, you can guarantee that I will throw a huge fit with the school district over there, and write them a letter from hell!!!. thanks again, I will continue my research and update you guys on the testing.
