There are medications the doctor can prescribe you and they do work. I can't remember the specific medication I was prescribed but my insurance would only pay for 15 a month. Apparently they are really expensive. Since there are more than 15 days in the month (uh, duh) I cut mine in half and it mostly worked. I was still somewhat sick but wasn't throwing up. I also used sea sickness bands (can get them at any drugstore) and I think they helped a little too.
Your OB will want to know you are this sick and can't keep anything down. I'm assuming since this includes water you aren't able to take prenatal vitamins and you certainly need to be taking your meds for the bladder infection so it doesn't get worse.
Don't tough this one out mamma, get some help so you can grow that baby!
If it's any consolation, I have heard morning sickness equals a healthy staying put babe!
Oh and I second the advice about snacking a little pretty much all the time. In my experience an empty stomach meant a sick stomach, also staying really hydrated was helpful. I think dehydration was why I'd feel so bad after waking up after a full nights sleep. And ginger (Trader Joe's has all sort of good gingery snacks).
