Getting used to handling & Shedding

I have a 7 month old Burm with a bad attitude. Over the past month I've been handling him almost every day(~10-15min a day, skipping the day after he eats) to try and get him used to it. He has gone from striking, biting, hissing, and musking/defecating to just huffing and blowing air when handled now. I've noticed that even skipping that one day after he eats he seems to regress a bit the day after. This morning he's in the blue. Should I keep holding him every day even though he's getting ready to shed? If not any suggestions? How about just just lightly petting him.

With All Due Respect,

Paul
