Damn, it’s like they don’t want you to get at the raisins. There must be a better way… You either mutilate the bag and your fingers, or cut it with scissors (or a knife - not recommended lol) , either way can’t be resealed without additional apparatus
You should check out the stop drinking community.
I do stop drinking, every day before I go to sleep 😋
If that works for you that’s great.
Just know that if the party is over there’s no shame in asking for help.
