I am addicted to snacks but I don't want to eat so much of them. I just got chocolate covered raisins and realized that it's a bad candy for me because they're small and need to be chewed so they disappear very fast and don't satisfy me so I just end up shoveling a bunch of them into my mouth. Plain chocolate tablets are better, but they still melt away pretty fast.

I sometimes buy salted pretzels, but I eat the whole pack in a day and then I feel sick and can't sleep well.

I need either something that's "healthy" so it doesn't matter if I eat them a lot, or something that I can keep in my mouth for a while so they last longer. I used to eat M&Ms, they're small and the hard sugar shell takes a while to melt, but they're not sold here anymore. I tried chewing bubblegum but it was just gross and rubbery and gave me an upset stomach.

What kind of snacks should I get?
