I am a coffee drinker as well - I used to survive on it! It's no wonder my adrenals were shot! LOL!
I couldn't even imagine being without coffee when I first started treatment with my current doc, so we came to an agreement - she wouldn't get on my case too much (
) and I would not only switch to the 1/2 caff stuff, but would limit myself to 2 cups a day, then if I
had to have another, it would be decaf.
Since doing this, I've noticed that I really don't do well if I have more than that much caffeine - so I avoid it the rest of the day. Even just 2 or 3 mgs (the amount in decaf coffees and teas usually) more caffeine after 3 pm can keep me up for hours past when I should go to bed!
