Help pls! How do you stop yourself from going over your IF window?

I’ve tried doing IF and always ended up accidentally going over my time or forgetting and having a snack.How long did it take to get used to and stop having cravings? Do you have any tips or advice on how you stuck to IF? I really want to succeed this time. via /r/intermittentfasting https://ift.tt/0tZTEfd https://ift.tt/bqCdnRp
