Hi, I had my SAH in June 2012 and like you got a little better and then started getting constant headaches ,bad tempered and depressed, my first yearly follow up scan showed all was well with the coils, I eventually after another year of constant headaches went to my GP who diagnosed depression and panic attacks ( normal for what I had been through) I had only been taking the tablets for 3weeks when my panic attacks and headaches disappeared , I began to feel more like 'me' again. I do still suffer from some headaches but not too many and have just had my 2yearly MRI scan . I am waiting for the results at the moment so will ley you know how I get on x Hope this helps, and please try not to worry x Good luck x
