Dear Cat,
Funnily enough, despite my forum name being Ducky for more years than I care to remember, I don't recall anyone ever starting with "well hello ducky", which they easily could and should have, "!+
How does a GP know which anti-depressant is most suitable? In the early-mid '90s, I twice took myself to the US as I also suffer from tension headaches (and migraines) and in the UK - "in those days" - they had no idea how to treat them other than with pain-killers. In the US specialist clinic, they would try various meds until one (hopefully) worked, they also pioneered the use of anti-depressants to prevent headaches; I tried various ones over there - amitryptiline, prozac, effexor - as I also obviously suffered from depression. The last two worked for a while. Once back in the UK I was able to see the top British migraine specialist who suggested Prothiaden which made me almost suicidal, so, because I also suffered from a form of OCD, I myself suggested Seroxat and have been on it ever since, which must be about 15 years. No one has suggested w/d from it and each time I have brought up the subject, the GP has said "now wouldn't be a good time" - mind you, this was after I had lost my son. But I think now IS time, good or not, as I suspect that after 18 months my grief has turned into depression.
I do, when necessary, take Rizatriptan for a bad migraine and I have read about the risks of serotonin poisoning or whatever ...
Anyway, thanks for listening,
Ducky
