Morning Sickness

My last pregnancy I had absolutely no morning sickness. This pregnancy has been different. I don't ever throw up. But I feel like I constantly have to be munching or sipping sprite to not feel uneasy. Does anyone else experience morning sickness/all day sickness this way? I get super light-headed and weak and my stomach gets upset. Not even close to actually throwing up though.

Kinda stinks cause on top of feeling like poo I am gaining weight from eating constantly. 😂
