I got a cleaner six months ago and it's revolutionised my life. I have M.E. and should have got one long before, I capitulated when I had surgery that left me incapable and I've kept her because she's an angel.
I run notes on my phone, one is a two-week ahead running meal plan and the other is a full list of the contents of my main and backup freezer. As soon as my weekly shopping is delivered, I book a new shop for the following week, and edit as I go/organise my meal plan. I keep my freezer list up to date so I always know what I have in, and I can use five minutes of down time when I'm out and about to meal plan and update my shopping.
Bought both kids minimum five lots of 'base' uniform (polos and trousers) and make sure they're clean, dry and on hangers complete with pants and socks on a Sunday night, we then just have to add blazer/jumper (they have at least 2 apiece) and they're ready for the day, for a full week.
Likewise put together five work day outfits on hangers on a Sunday night complete with underwear, socks and matching scarves and have them hanging ready, I just pick what takes my fancy each day. No stressing in the mornings.
Buy cleaning products I like using (I'm a sucker for Method) - they are more expensive but make chores more bearable in between cleaner visits.
Frozen pre portioned smoothie packs mean I'm now having a smoothie every morning and getting more fruit and veg. I also make my own juices a few nights a week and freeze in portions.
Batch cooking on a Sunday if I can stand up long enough, for the fridge and freezer. I will prepare the filling for, e.g.,veggie shepherds pie on a Sunday and on Monday/Tuesday take frozen mash out in the morning to defrost, ready for coming home at 6pm, when I can just chuck the potato and some (gasp-pregrated) cheese on top of the filling and hung in the oven.
