You could try giving yourself a challenging mental chore to do. (alright I'm nuts). My story goes like this..... At the beginning of April, I decided to set up a Blogspot on Google. Partly to challenge my limited computer skills. I stayed up til 2.00am in the morning 2-3 times & spent most of several days trying, going over & over the instructions on how to use a Google Blogspot template. I was determined to set it up & despite fatigue, I stuck at it until I managed to work it out - took me 2 weeks to understand the instructions. I kid you not. I am hopeless with a computer. In the meantime, I wasn't hungry (despite my usual snacking habit). In other words I was eating out of boredom in the past - not hunger. I felt "hungry" before I finished full-time work. I had a busy job, even a stressful job. But that job wasn't ringing the right bells in my brain. I needed to challenge myself with something that I desperately wanted. I didn't want to do more computer work when I was working, as I was exhausted all the time. So while I had the desire to set up my own blog, I was too fatigued to attempt it. But now that I'm not working, I am not so tired. It had to be the right "challenge". My intermittent brain fog stops me starting many tasks in recent weeks. But setting up that Blogspot was the right challenge at the right time. And I knew it didn't matter what time I went to bed, as I didn't have to get up for work in the morning. Any chance that you can find something that distracts you enough, is so challenging that you can't put it down, & is doable. Now that I've got past the so called "hungry all the time" mental state, I seem to have cured my habit. (I might add that if I eat foods that don't agree with me, I can revert back to that hungry all the time habit). So try not to feed the idea of "hunger all the time". You could also try drinking a glass of water every time you feel "hungry". I've never done this, but have heard that it succeeds with some people. High protein/low carb usually makes you feel fuller too. High Carbs usually make you initially full, but don't necessarily last long. Doesn't work for everyone, but if I eat carbs like bread or pasta, I seem to get hungry quicker (than if I eat steak & steamed vegies).
