Oh the poo issue

. for years if my bowel became irritated in the early hours I would hold on in case I had picked up a bug and it was the runs

so U are not alone in this. I must have spent 1,000s of hours over the years awake in the night, when I did 'go' it was within normal limits. But I never learnt!
Try eating little and often B4 the body gets hungry. Snacks: bananas, dried fruits/nuts, keep hydrated; ignore the sugar issues at this point in time as the body requires natural sugars. Pancakes are a good standby, mixed in the morning and cooked B4 feeling hungry, the batter keeps for 2-3 days in the fridge. It's what my DH cooks if I have a dip. Banana on toast ........... Marmite on toast or Bovril in hot water to drink.
Any rice/chicken mix is protein and filling.
What's the peri check list I wonder

. As oestrogen levels drop muscles may become lax ........ gentle walking in early morning/late evening sunshine won't do any harm. Let us know how you get on.
