I'm only 7 weeks along but I feel miserable already. About a week ago, I went from no pregnancy symptoms to BAM! all of the sudden I've got awful morning sickness, headaches, I'm freezing all the time, I can't sleep at night, etc. etc.

I think I've even started losing weight because keeping down water is an accomplishment, let alone any food. I can't eat, I can barely drink, and my stomach is so sore. Any suggestions on how to deal with this all-day morning sickness?
