Help me out!

Recently I've been getting a lot more hunger a lot sooner than I used to, I wanna fall asleep at work majority of the time & by the time I get home I'm ready to take it down for the night & this morning I almost threw up but I didn't allow it to come out my mouth (I know that's gross, but I ABSOLUTELY HATE throwing up).. Can someone give me some ideas of what they think js happening??!
