Feeling so sick

I had my first injection (2.5mg) at noon on Saturday. I hadn’t had much to eat before then A few hours later I started feeling nauseous. London fluke morning sickness and just not interested in any food. I tried to snack on small things, drink protein, water and electrolytes. I took a Bonine to try to help. By 9 pm I threw up. Felt immediately better, drank some more fluids and we went to bed. All night I was mostly okay but around 5:30am I felt really nauseous and ended up throwing up again. So now I’m lying here regretting this decision. Does it get better? Has anyone else experienced this? Any tips to help curb the nausea and vomiting? Maybe I need to decrease my dose next week?
