I am definitely a "coffee" person, having written several previous posts about my coffee machine, however, oddly, I wake up and have a cup of tea, usually the only tea I drink as I don't really like tea.
Definitely not. Went to a yoga retreat at Mangrove Mtn in the 'seventies and have followed the Swami's advice ever since - clean your teeth, scrape your tongue, then drink a glass of water. If you go straight to the hot drink, imagine how much muck you are swallowing.
I haven't drunk coffee for years and don't miss it at all. I find a great (and healthier) way to get my day started is to add a little bit of fresh lemon juice or apple cider vinegar to water, and to drink that. Nothing like coffee...but it works!
