hmm, can’t seem to post this one last try:
I’ve had insomnia almost every night my whole life, so long that I thought it was normal until relatively recently. Also because it was so prevalent, I never noticed any correlation with food consumed until recently, when, for only vaguely related reasons, I simplified my diet pretty drastically, and noticed that as well as my sleep improving generally, I also started to spot correlations between things I ate and how I sleep.
One of the things I have found to help is parsley, and for yesterday’s evening meal I experimented with adding a load to some braised leek and onions. Flavourwise it was good, but I was horrified to see that, on waking for the second time, it was only 1.45a.m. Wide awake, I gave up on sleep and started mooching on the ‘net, and for obvious reasons this thread title caught my eye.
By a fluke, I think tyramine probably explains tonight’s shocking level of insomnia, possibly made worse by consumption of refined carbs, but I had the same carbs the evening before and tonight’s insomnia is much worse.
Also for supper, I had a big chunk of blue cheese, normally I have no problems with blue cheese, but this piece had quite a whiff of ammonia, i.e. it had fermented . . .
How badly something like this affects you depends on a whole lot of factors, including your own enzyme system, what other foods you have eaten, or drugs you are taking, as well as your gut flora. They all affect each other to a greater or lesser extent.
