I buy cheap coffee. Coffee to me is like beer: it all tastes like shit. I drink it for effects, not taste.
A few years ago I started using instant coffee but holy crap it irritates my throat. Very acidic.
So I came across Betel nut on Amazon and ordered some. Damn I loved it. It tasted OK and had a great 'pick me up' effect. However, after 2 orders it became illegal or , more accurately, regulated in the States and now I can't find it anywhere.
