Hiya, welcome back and good luck on your restart. What type of shifts do you work? I work 2 x 12h dayshifts, followed by 2 x 12h nightshifts. I struggled initially (well, until last week really) until my CDC suggested that I split my packs in half to make 8 meals instead of 4. I found that this has really helped and I've also planned the times I would be eating to ensure that I didn't have too many packs in a 24h period.
Hope that helps?
Take care.
Tess
