So have I. At 33 I decided fuck it. I’m going to drink coffee everyday until it works for me. And after 1-2 weeks it worked out. I still get stressed out, and if I drink more than one espresso I’ll get anxious, but I can drink one coffee per day now and it brings me SO MUCH energy it’s crazy.

Btw the same was true with weed. Weed used to make me sick like hell. I decided to just keep smoking and in a few times my body just adapted to it. I can’t smoke too much otherwise it’ll get mental, but I can smoke a bit and be happy.
