Tackle night first. If you get your sleep you feel much better for it.
There is diet advice that it is better for you in general to have no food for 14-15 hours at a stretch, and confine meals to the other 9 or 10 hours. I stopped eating anything after about 6 pm, except a couple of dry crackers if was hungry in the evening, with a glass of water to wash them down. I didn't drink anything milky after 6 either, just water or weak tea (Earl Grey decaff) without milk or sugar Beside my bed I kept a packet of Rennies, if it still threatened I sucked one of those slowly. I used two pillows instead of one, so that gravity helped.
By 8 am I was ready for my breakfast! Porridge the Scottish way (made with water and a little salt, no sugar, milk or other Sassenach additions, with a splash of evaporated milk on it in the bowl to soften the taste (traditionally it should be single cream or top-of-the-bottle, but I don't like cream, particularly at that time in the morning) Toast, butter and marmalade with home-made bread (fewer additives) and decaff coffee.
I stayed with the decaff through midmorning coffee.
Midday is my preferred time for a main meal (probably very plebeian of me, but that was how I was brought up) It gives time for digestion before lying down at night. I didn't try to limit how much I ate then, but I tried to be conscious of how my choice of ingredients affected my digestion through the day - though that was less a problem than at night. Very strong flavours and spiciness, and too much tomato, were not good.
Teatime was a light meal.
Through the day the crackers and a bit of cheese filled up any hungry holes
I now very seldom get a problem, usually after overdoing the rich food that someone else has lovingly prepared.
My eating pattern is still about the same - there is a saying that you should breakfast like a king, lunch like a prince, and sup like a pauper.
