Paxil killed my sex drive too. Luckily I was single during that time, so it didn't affect me too much, but I noticed that I wasn't even aroused like I used to be when I was on it. I've switched to Pristiq since and I'm better. Paxil also caused a lot of weight gain, another reason for me to get off of it. Although my mood was so much better, just couldn't take the side effects anymore.
