I thought I was through the worst of m/s but last evening I began to vomit at 6:00... a lot. I had my prima bella watch on, took zofran and continued to get sick. At 8:00 I took phenegan and soon after got sick some more. I called the on call dr at 10:00 to find out if I could take more meds seeing the previous ones may have come up... he said more zofran and that typically it's no harm to vomit like this for 24hrs straight without keeping anything down. That just didn't seem right. I was already beginning to feel dehydrated a little and the thought of sitting in the ER for hours while still vomiting just wasn't an option. Eventually I stopped and slept. I was able to keep liquids in this morning which was good but still feel like I could start again at anytime. This m/s is kicking my butt. I dont't know how much more I can tolerate.
