Q: Do i need to spit the final rubber thing? i used altoids, and i dont have to spit anything.

Spit the final rubber thing??? It's gum, of course you need to spit it out.

Q: Is this aspartame free?

Not only aspartame but sucralose (chlorinated sugar).

Q: Why has the price of this gone up $5. I paid ~$15 a few weeks ago and now it's $20. Why?

Different sellers. Don't buy it until you find it in the price range you are looking for. Stores charge 4.00 for one so I judge whether or not I use Amazon depending on store prices. Amazon is not always cheaper. Sometimes they think you are too lazy to go to the store.

Q: How much caffeine (from the green tea extract) is in each piece of gum?

I have dry mouth syndrome and I've found that Mentos are ideal for keeping my salivary glands working, especially since they are sugarless. I chew at least 2 or 3 pieces a day.
