OK,

I am going to wade in here. I am a retired psych and your problem is one of breaking an old habit..the eating pattern is part of a cycle that also involves using eating as an excuse to not study.

Here's what you do. Have a neat magazine nearby. Note the time and allow yourself no more than 15 minutes to study, and work at concentrating. If you can't manage this, then bring it back to 10 minutes to start off with. After the short bout of study, you then take a 5 minute break and look at the magazine...no more than 5 minutes. Then back for the next 15 minute study stint, and so on. over the ensuing weeks, gradually increase the study period time, but never exceed 40 minutes, which is about maxixum concentration time for anyone. Allow your self to make a cup of tea as another break or as part of the 5 minutes' break with the magazine.

I used to study with a friend, and we would study for 40 minutes, and play a game of cribbage for ten minutes' breaks, with a cup of tea.

It is just a question of learning new habits and breaking old ones. You only need to apply the same
dedication to doing this as you did to reaching goal weight. The well meaninged advice regarding food substitutions will not get at the problem as it still involves using food thoughts to break up concentration.
