1 day out of 3/4 I have MW - the rest... mmh, not happening. :-\
But please don't take my case as the 'standard'.
also you have a girlfriend and you're not shunning out of sexual relief either (like I was forced to do for a while)
. I think it may be related (MW and sex, I guess). I've felt much more libido and sexual desire now that I'm back in the dating game again.
