I started on nortriptyline 10 mg/day in July 2015 after being diagnosed by Dr Surenthiran. It helped alleviate my symptoms of MAV almost immediately. Since then I have titrated up to 75 mg/day, which I have now been on for several months.
The nortriptyline has greatly improved my symptoms without completely eliminating them. Dr S. added pizotifen 1.5 mg/day at my last check-up but I haven't noticed any effects from that at all (neither improvement nor side effects).
The only bothersome side effects from nortriptyline have been dry mouth, constipation, and intense dreams. The first two can be alleviated with various products, but the intense dreams persist.
