He is being weaned off of Pamelor because it is no longer working.. I hear good and bad about the Intuniv. My son is a tiny thing 44lbs. i want to try this medication for both ADHD and Tourettes because I have read that is is good for both. Im concerned about his weight, he is a picky eater already and has anxiety at night when off his Meds? will this possibly make his sleeping bad again ? what do you think? Thanks , firelady
