Perhaps you could start a behaviour chart.
A daily chart sectioned into time frames, hourly or whatever, and you can mark your basic routine in, some people have a key for set behaviours Ie #- licks etc.
There maybe a pattern, when he is tired he may do something. If you could keep a food diary too it could help.
Just ideas, not sure how practical they are for your situation.
Keep in mind that some of us don't fit entirely into 1pigeon hole, but can be bits and pieces of a few.
