I've been treating my migraines with a verity of different things for the past year or so. I've been on Nortriptyline for several months now, my dose was recently increased to 50mg, because the headaches came back much worse and much stronger. The increased dose seems to be working as of now, my question is does anyone find that when they do get headaches/migraines now, that they are worse then before? Even debilitating? Immatrex had been working wonderfully for me up until this point, it seems as though it isn't strong enough anymore. Thank you for your help.
