D.M.
sounds like morning sickness which I had for three months with my daughter (it was bad!) and three months with this baby to come. I would take the medicine. I haven't had anyone tell me that's taken it that it's made them real sleepy so you might be okay. Have you tried drinking Sprite and eating Saltines when you have this feeling or even Ginger ale? Either helped me a lot! Good luck and hopefully it only lasts a few more months. Congrats on pregnancy. :)
