I can't offer too much help Coppperbelle other than to say that Apo-Amitriptyline worked much better (and quicker) for Lucky than Clomicalm.
We've consulted with Dr. Enid Stiles at Pierrefonds Animal Hospital and Dr. Diane Frank at St. Hyacinthe (they often work together as Dr. Stiles studied under Dr. Frank). They are both amazing doctors. Dr. Stiles did the initial assessment but we have our vet, Dr. Gilmore (Animal Health Clinic, NDG) follow-up. He's the one that suggested the Apo-Amitriptyline as he has a dog with SA as well and is quite experienced.
The Apo-Amitriptyline can also be bought at a regular pharmacy at a fraction of the cost of the Clomicalm as well. We paid about 16$ for a month's supply.
