Olaf. In the dozen or so posts that I have made on the subjects of depression and classical migraine, I have had to state that I am a pilot and not a doctor. My comments have been made as a layman, but with the best intention and a tad of skilled back-up.
FD makes two succinct statements specific to aviation, you have to be guided by them.
Daina has put into one post, probably everything that I have tried to say over the last two years. I would however, ask one question. Are you currently, or have recently, taken any other type of drug that has not been discussed? You have some skilled people listening, now would be a good time to really thrash through this. The ultimate aim must be to be free of any drugs of this kind while flying.
