Wow! That lapse of memory is the sort of thing I could do, @Brunneria . Aside from your mega-spike, which probably knocks you a bit, do you experience any other symptoms immediately when you gluten yourself? These days in addition to the fatigue etc, I get a splitting headache. I feel your pain, with that to get over, as well as your virus.
Oddly, gluten does nothing to me for around 24 hrs.
Then I get itchy ears. Inside, down near the eardrum. Drives me insane! Lol
Days 2-3 my guts set like cement.
And days 4-14 i get psoriasis in hairline and around ears.
Knee pain on climbing/decending stairs for about 10 days.
You couldn’t make it up, could you?
I spent ages trying to work out what was causing it, but the symptoms are so bizarrely unconnected, I didn’t twig until we went on hol for a week to Northumbria, and I declared a Low Carb Amnesty for 1 week, and ate Bannock, toast and scones. Delicious!

Ended up unable to climb even 3 steps at a time. It just got worse and worse. I was hauling myself up by the bannisters. And wondering if we needed to move to a bungalow.
Stopped the gluten on the drive home.

2 weeks later, the symptoms were fading fast, and completely gone at 6 weeks.
That brownie today was a major lapse in judgement!
