Started drinking at 29 but felt nothing

Long story short: I’d never drunk alcohol in my life, for a bunch of reasons. But after a very sudden separation from my husband after 14 years together, I started questioning a lot of things about my life and wanted to try alcohol.

I bought a can of Suntory -196°C Strong Zero (I live in Japan, and it’s a pretty famous drink here with 7% alcohol) and drank it, but it didn’t really do anything to me. I just felt warmer than usual.

Do I need to drink more? Try something else?

When are the supposed pleasant effects, like relaxation, meant to kick in?
