Multiple people here have that issue, its discussed unde the post - " waking up refreshed a thing of past ?". You should definitely check it.
I dont feel any dizziness as such in morning or the day although I have cutback sugar alot in my diet. My morning routine is pretty simple. A cup of tea with 3-4 brown bread with butter and 1 bread with peanut butter. One scoop whey protein before I leave for work.
I do a light lunch some eggs and rice and black coffeee or another cup of tea. If anything I do eat a lot of bananas as I read about low potassium with a jpouch.
