“this doesn’t taste of anything” a disparaging remark

“I can’t feel anything” rather alarming at times

Do they have a partner or a close family member you could talk to? When I had a spending problem the only person that could help me was my partner. I put them in charge of my finances,l – gave them my cards, made sure to delete saved payment methods online – so I had to justify purchases to them first. They’d never say no to anything, it was my money after all, but having to justify my spending and taking a moment to consider really helped.
