Hi @Smudger just popped in to welcome you to the forum 
I’ve no experience with anti-depressants to offer advise on, but don’t ever feel you shouldn’t post, you had a stroke, a TIA is still a stroke and you still matter! 
And @Rups might be the one to discuss this with as he’s currently weaning himself off them I think, which is why I’ve tagged him in. This is one of his posts on the subject from last year, there may be more if you care to search under his name in the meantime
And exercise is my only drug of choice, keeps me high most days
