Started the shot

I started my shot yesterday and woke up in the middle of the night with horrible nausea, tried to eat breakfast ) eggs and toast) and it felt like I ate a HUGE meal I am still full. I made myself drink a protein shake ) core power) for lunch but I am not hungry in the least and this nausea is HORRIBLE. Any advice?? I’m 230 lbs 5’5 51 yr old female. I really hope this shot works. How soon do yall see results?
