Caffeine is a big one for me. I realized how much it affected me too, even in things like green tea and hot chocolate.
Instead of meditating, I started journaling which helps to slow the mind to a speed that I can type.
Exercise; I do need to start that but I'm so far convincing myself to do cleaning and maintenance instead... which gives me the joys of a tidy home too.
Slowing down and not trying to do too much has helped a lot...but I also get anxious from procrastinating and letting things build up. So I need to strike a balance.
But thank you for your article. It's reassuring that it's not an uncommon problem
