HELP!!!My pug ate a quarter bag of peanut M&M's!!!?

I got a medium sized bag of peanut m&ms. I ate around 1/4 or 2/3 of the bag(The Majority). I kept the baggie on top of my fridge. I walked in the kitchen and saw my 2 year old, 20lb pug eating a ripped bag of m&ms. So she only ate about 1/5 of the bag. She is sleeping but looks uncomfortable. Will she be okay? What should I do? Please Hurry
