LOL twizzlers are awesome.

Just about everything can be found in Negril but I do bring a big ziploc bag of raw almonds and cashews because I can get a really good price at them at the store by my house. I also bring hot cocoa packets for the kids (w/marshmellows) even tho I can get them there too but get at the $1 Store here. Last few reaches I took a bunch of Cilantro and made homemade pica del gallo (tomato, onion, cilantro, hot pepper, garlic) which is great w/tostitos or on fish/chicken........

Few snacks I LOVE in Jamaica though are:
--Shirley Coconut Biscuits (shortbread cookies) they are so delish!
--I love cheese and water crackers (wheat cream I think is my favorite brand)
--Fresh fruit like mangoes, guinnips in season, sugar cane
--Hot roasted peanuts from the peanut cart that whistles up West End
--(kids love all the horribly unhealthy chips and juice that are so cheap but I steer clear)

I don't snack too much though - Fruit/toast for breakfast; light lunch and nice hot cooked food for dinner.
