Hiya Christine, sorry to have taken so long to get back to you. I came across the opioid idea when I was looking into why I reacted to wheat and dairy. I gave both of those up right at the start upon the recommendation of a friend and I kept off them too when taking up the headache diet. Every time I tried either, it affected my measure of dizziness. I can tolerate a teeny bit now but mostly I really don’t bother any more, not worth it.
Anyway, I found out from my reading that both wheat and dairy contained opioids and when I looked up what those could possibly cause sensitive individuals to feel I thought “Aha”, that sounds like me. Further clues followed that I might be reacting to opioids: when I left wheat and dairy off I felt SO bad, just like when I was coming off benzos in my twenties. Similar disorientation, weird and dizzy feelings; VERY similar feeling to when I used Feminax in my teens for period pains (contains codeine which I didn’t know back then); when I had morphine during my hysterectomy afterwards as I slept/dozed I could feel how I do just prior to a bad vertigo attack (which never materialised though). The common factor in all of those was opioids of some sort. So it dawned on me gradually that my theory of the opioid connection might be right.
The spinach episode was the clincher. I had no idea why I had reacted to it. But, playing detective as usual, I found out about the rubiscolin. Lightbulb moment again!
I’ve found a few really helpful web sites, one a blog, where folk seem to have the same reactions to opioids as I do and who came to the same conclusions. I don’t think I have kept the links though. But I’ll have a look and if I can find them I’ll post them.
As I said, I do seem to be able to tolerate teeny weeny amounts but with me a cumulative effect seems to be in operation. Like you, I went a bit mad over Xmas, thought I’d got away with it but after fours days (it’s nearly always three or four days, trying to work out why)it hit me bad! I felt ‘out of it’ and totally disorientated, had trouble with lots of things I usually cope with OK now. One thing I have noticed, once I indulge I almost feel addicted and can’t stop wanting to have more and then more still… far and above just being greedy. You used the term ‘slippery slope’, it’s a good description!
Hope this sheds a bit of light on the subject, although only my personal experience,
