I was on sertraline years ago for anxiety, they worked for me.
Didn't notice any side effects from them, although I was distracted at the time,
with everything going on in my life.
Then one day decided to come off them, which I did gradually.
But, yeah, they worked for me, but like we said on another thread, what suites one, won't another.
I'm sure you'll be absolutely fine going away for Xmas, hopefully they'd have kicked in by then and you'll have a great time.
Keep us informed how you're getting on.
Good luck..
