Yeah of course I do. I like chewing them before games or during them, they help me concetrate better.
I always have a pack of gum in my car for guests, or when I feel like I need to have some. But, I'm the type of person to ALWAYS try something different every week. I love trying out new flavors, and seeing which ones are good, and which ones aren't. Currently, I'm trying out the new Stride sweet melon/berry flavor. It's got a good taste, but I'm not impressed with the texture, or the fact that the flavor doesn't last very long. Also, it's kind of tough, so your jaw definitely gets tired after a little while.
This is what I'm chewing right now. Love it. I drink lots of water after lunch here at work and, for some reason, the aftertaste is kind of gross, so I chew gum to get rid of it.
No, ruin your teeth instead. When you scratch off and win, you lose. By winning, there's a 99.99% chance you will buy another one. When you lose, you win. Each time you lose, the chance of you scratching your money away lessens by greater than 15%.
