So nauseous

I’m 7 weeks 5 days and so nauseous. It’s just getting worse and i have a feeling I’m going to actually start throwing up soon, i had awful morning sickness for the whole first trimester with my son. But as of now, i keep feeling like it’s about to come up so i go to the toilet, and all i do is gag and that’s it. What can i do to help with this?? I don’t remember really taking or doing anything to help during my first pregnancy, but I’ve heard sprite. But sprite is one of those sodas that i feel is definitely going to trigger me to throw up. It always has( only when I’m nauseous of course).

Also, is it just me or does it take so much energy to do anything😭 i get out of breath so easily and everything i do feels like so much effort. I feel like I’m in my last trimester 🤣
