My desire to hang out with people is pretty much gone too. My poor friends. Parties are a chore. Going out to dinner is a chore. Talking on the phone is a chore. If you don't have email or IM, good luck chatting with me. My desire for sex is gone too. My husband is a little freaked about it anyways though he knows it won't hurt anything he's pretty much ok with my dissipated desire. No desire to exercise. I think I'm more afraid of exercising than the lack of desire. Lack of creativity which my job sometimes depends on.
Being knocked up is tough!
