Hi, I expect that I will get castigated, I normally am, however, did you eat bread the day before, or the period before. Bread always does this to me so now I try to avoid it. People will say that its not hard wheat, to that I say Hmph.
Put it this way, if not eating bread stops the problem then what is the harm. I have put up with this curse for 15 years now and if I have discovered nought so be it.
The University hospital at Nantes confirmed that if I ate bread then not only do I fall asleep, but that the next day I am tired, lethargic, miserable a pain in the proverbial etc. A small bit does not cause me too much harm.
Anyway you can ignore or try, it is up to you, give it a week without bread, and for that matter anything with hard wheat in it, cheap beer, blended whisky, some ice creams, cheap cakes, pies and so on. Even watch your pasta, I have found some of that made with wheat as opposed to Durham wheat.
Regards Roger.
