You can definitely get used to it but THAT fast? I've been slowly eating more and more spicy the past year going from Sriracha to ghost pepper. But it's addictive, I put something spicy in almost every meal now. If you like chili see if you can find a shop selling Mexican snacks and salsas. If you're in eastern Europe another alternative is Hungarian paprika which is a different flavor but can get very hot too.

And it seems my local imports store also sells these chili strips so now I gotta try them.

Be advised that different cuisines use different chillies which hit differently.

I lived in the US for a few years and when I went out for curry, the staff would warn me that some of their curries were hot... until they realised I was a Brit at which point they were like 'ok, enjoy'. I could out-spice all of my American spicehead friends with curries. But some of the Mexican food I tried blew my head off completely while not especially bothering my American friends. I got used to that too but it took some acclimatisation.

It's definitely an acquired taste you can get adapted to! Ever since I got into spicy foods, I've had to have extra chilli ever since!

Kettle brand Habañero Lime are my current fave, but I can only eat a handful at a time. And if you have a Kanker sore or something, then just forget about it lol.
