What you can do is imagine you’re eating the food you want to eat, or if it’s during the day and you want junk food, just imagine eating that food. Then have a few sips of water and see if you become satiated after 10-20mins.
Also, as I’ve titled the post, “Eat a book”. Lay in bed and read, or chat with someone else over the phone.
Lastly, “just do it”. Not the militant type of way, but as a self loving act. See if you feel better in the AM and always refer back to that to use as a motivational factor for the next evening challenge, as well as looking back on the painful memories of waking up extrea groggy.
