I can't really answer your specific question but I'm getting a cervical fusion and once I get the green light to train I'm going to "try" to come back. In the meantime, I'm going to just let my bodyweight drop and drop my food/protein intake. I know my body comp will take a hit but I think I'd rather let the weight drop than try to maintain weight, get fat, and then have to shed it all off.
But to possibly help answer your question. Once I get back at it and going I think I might try using Lantus 1-2x per week on high carb/low far days. The idea would be start at 30iu 1-2x a week and then progress 10iu per week until I hit 100. It's def a steep dose but only only it 1-2x a week I don't think they'll be any issues with IR. The other days, GDA's will be in play.
As Virtuous said- also this: Zero alcohol, slept 8-9 hours/night, ate like a horse, trained hard as hell
