Hi Molly....it's definitely running out of Dosulepin that's causing the 'crash' that you're experiencing. I've been on Dosulepin for over 25 years now and even a few days without them can cause mayhem. They're an old Tricyclic drug that have been around for years. I would definitely ring your surgery and DEMAND that you have them. But when you get them, whatever you do don't make up for lost time and take a bigger dose(unless the Dr. says so). Get onto the surgery a.s.a.p.!
