Don’t start with expensive stuff. Not even Starbucks. Just go some place and ask for a cup of coffee. Some tastes you will like. Some will be too strong, while others will be too weak. Find one that you like. See if you like it black, or with cream, or sugar, or both. Again, it’s your taste. See if at affects your sleeping (caffeine) or not. At least at first, only drink it before noon. Be aware that – especially in quantity, like more than 3 cups /day – coffee can affect your stomach and create all sorts of problems. In my opinion, there is no difference between a dollar cup of coffee and a $10 cup, except the price. Of course there will be plenty of snobs and pseudo-experts who will disagree, but that’s my opinion.
