Advair HFA and skin tests

My son is 9 years old and started on Advair in April of 2004. Thing is, it took us forever to get a diagnosis of "asthma" from the allergists. He spent some time in the hospital as an infant with "croup" - sent us home with a nebulizer and some albuteral - He was a monster while on albuteral! So active that he bounced off the wall. Anyway, as he grew older we had him tested and the skin tests always came back negative. Last time tested was in April 2004 when he showed "slight" allergies to "the usual suspects" - pollens, etc. (but honestly all the spots on his back looked the same to me). Anyway, allergist put him on Advair and things went pretty well over the summer. Now school is back in session and all of a sudden my son is a horrible student - he was tested as gifted in kindergarten - but now he cannot sit still in class - I keep getting notes from the teacher saying he cannot stay focused enough to finish work in class. he is missing recess to get caught up and still bringing work home to finish that he did not finish in class. Homework is a horror! Tonight we started at 5pm and did not finish until 7:30 - Gifted teacher gives me same report - he just can't seem to finish his work. He is driving us nuts! The only thing different is the Advair from last year to this. Could it really be the culprit? I am at my wit's end and very tired of being angry with him. I watch him work and realize he is everywhere in the room except where he is supposed to be - looking at the ceiling - tapping his pencil - walking in circles - having to go to the bathroom - going into some long, involved story that he HAS to tell us - but not on the paper sitting in front of him. When he actually DOES the work it is 100% correct. I am so interested in hearing from other parents with young children on Advair to see if it is just me or if this is a common - or at least feasible - reaction to this medication. You can contact me at kathryn.gritts@lcms.org - be sure in put asthma in the subject line so I know its not SPAM. Thanks so much. I don't know what else to do except have him tested by a psychologist for ADD - but it seems odd that this didn't show up in K thru 2? Thanks!
