I read online that the average time from conception to the onset of morning sickness is 5 1/2 weeks. At precisely 5 weeks and 4 days, I came down with something that reminds me of some of the hangovers I had in high school after a few too many Bartles & Jaymes wine coolers. Bleah! I'm trying to stuff some oatmeal down my gullet so that I can take my vitamins and aspirin and Es7race. Eww.
On the plus side, I don't feel overly tired yet (except for the weakness from my not being able to eat or drink much), and my boobs don't hurt at all.
