I ate a boiled egg for lunch. With salad. Hadn't eaten since 8 last night (16:8). It was cooked properly, barely soft. They aren't old eggs, I bought them this morning.
A couple of minutes after, I started feeling sick and had to actually hang over a basin and was proper retching. Nothing came out though because I'd only eaten the egg so far and somehow that stayed down.
Something similar happened to me previously, I'd had omelette and salad a few days in a row, i think it was when there was that thread about whether an omelette constituted a proper dinner or not, and I kept fancying one. Anyway, this particular day, I was halfway through my omelette and came over proper heavey, full on saliva, the lot then too.
But I'm not allergic to eggs 🤷♀️ as far as I know.
