Bless you, this stage is really hard, especially managing on very little sleep!
I would address sleep first. You decision making, blood sugar control, hormone regulation all goes pear shaped when you don't get enough sleep. You can't pour from an empty cup!
First, talk to your OH and spell it out that you're running on empty, and it can't continue. Get him to get up with the kids on weekends so that you can catch up on sleep. Negotiate that down to just one day a week if he really makes a fuss.
Secondly, as tempting as it is, alcohol and sleep really don't mix together well - alcohol fragments your sleep so you wont get a restful night even without toddler wake ups. so I would try to limit that to a couple small glasses with dinner on the weekend.
Thirdly, go to bed with the kids. You can't do anything about what time your toddler wakes up, but you can control your bed time. No, it's not fun, but you need to put your health first. You'll be able to tackle the challenges of the day so much better when you've had some more sleep! Put your phone away, switch off the TV, and just hit the pillow. 7 hours of broken sleep is still better than 5.
I would give this at least 2 weeks. Then, once you've somewhat caught up with that, I would tackle your diet in this order:
- Junk
- Breakfast
- Evening snacking
- Lunch
- Dinner
- All other snacking
So with junk, the aim is to reduce it, and to be realistic about it - consistency over perfection.
Environment is the invisible hand that shapes our behaviour, so I would aim to remove all tempting foods from your house. If they are not there, you can't eat them.
If you cant do that, then at least put them somewhere awkward - higher shelves, behind other jars so that you have to take other stuff first to get to them. This will stop you mindlessly grabbing stuff and shoving it in your mouth.
Be realistic - you will want to snack, so get some healthier options, like fruit, veg sticks, cherry tomatoes. I don't know many people who can eat more than one apple in a row. I can't say the same about chocolate Digestives!
If you have access to cakes and biscuits or vending machines at work, then obviously there's not much you can do about that - so set yourself a weekly limit, ie I can have 2 treats a week - on Thursday and Friday. That way it's not a taboo, but still a reduction, and something to look forward to at the end of the week. As above, bring some fruit in so that you can have that if you're really tempted.
Do this again, for 2 weeks, and then aim to reduce further, or if you feel that sweet stuff is more or less under control, then start looking at your breakfast, as that really sets you up for the day. And so on.
You can do it, but you need to put yourself first ❤️
