Hi Will, I've been taking citalopram 10 mg. for a couple of years. There have been a couple times where I have ran out before I could get to doctor for refill (no insurance) and I can actually tell a difference in my SA and depression.
In conclusion - yes, they do help. My doctor moved me up to 20 mg. once and they made me too tired during the day so he bumped me back down to 10 mg.
You do need to give it longer than a couple weeks to get in your system so hang in there and after a couple months of taking it, you see it's not for you and not working, tell your doctor - I've had to experiment with what works for me and what doesn't .... not unusual.
Hang in there and let me know how it goes
Good Luck!
