I’m proud to say that I have never drunk a cup of coffee in my life. If you never start, you can’t get addicted. I think it’s a bad sign if you are so addicted that you have to start cutting back before Yom Kippur to avoid withdrawal symptoms.
Any health benefits that may come with drinking coffee can be gained from other sources that don’t also come with addiction and jitters, like tea. Tea is healthy, refreshing and delicious (and won’t stain your teeth like coffee and soda!) But no matter which hot drink you choose, you should also make sure to drink lots of water throughout the day, particularly if you live in a hot climate like Eretz Yisroel.
