has anyone had problems with Topomax and sex drive. I have noticed that since I began on it that I have gone from daily sex to none. Has anyone else had this problem?

I have been taking Topomax for three weeks now(started at 35mg and now up to 70mg a day) and noticed that my sex drive has all but disapeared. Not my abilities, but my drive. No interest whatsover. Prior to that, I had sex every day. Has anyone else experienced this? Any advice?
