Is it normal stopping soda made me this hungry?

So generally I drink a lot of soda and a ton of coffee. Coffee has three times the caffine that soda does. I stopped soda for about a month now and my normally high levels of energy are extremely low. I also get super sleepy when I dont have soda or caffiene regaurly. After a few days I started getting an extreme hunger that wasmt going away so binged on fast food, starbucks and soda. I feel semi okay right now. I realize now I might just need soda on a regular level becuase I need the sugar. I also eat a lot less when drinking soda.
