I eat a lot of spicy food, a lot of curry, a lot of chilli, mainly vegetarian, so my body is used to spice and fibre.
BIL is Indian so sometimes proper authentic Indian cooking. And my dad likes a HOT chilli, so if I eat there it's prepared to silly levels of burniness!
And it's not as if a takeaway is a RARE treat, we have a couple a month (from different takeaways too, so it's not just a dodgy restaurant?)
So why does it have this affect on me?
