Smudge still scratches himself to excess sometimes, especially when the weather changes in the spring and fall. It used to be much worse, big bloody lesions on his neck and face! The vet suggested an antihistamine, which I put in his food twice a day; and I experimented with kicking out various foods (I now know not to give him anything with Aspergillus niger in it - it's often found in dental supplements and treats). He still has rough weeks, but he's much more comfortable. Definitely ask the vet.
