So we all have been there ! Had taken tea or coffee on empty stomach and then dipped a biscuit or toast! I am generally not a squeeze a lemon in water ( again causes acidity ) for me ! I have been there too and guilty as hell .This have had bad implications in gut health primarily making you acidic ,giddy ! Avoid this … Try to first have some nuts or biscuits or even a fruit and then go and have your tea or coffee after a bit ! I generally have two cups of coffee in a day or maybe a tea as well ! There was a time when I could have 3-4 .But yes 2 is just fine .Yes coffee lover ! Would love to know your thoughts or your own bit of experiences on same !
