If this is your first time, trying coffee
on a daily basis, you may want to start with a small cup, to find out how
jitterey you will be feeling, about half an hour after you drink. I have gotten jittery before, but then I just eat a meal.
I am in the San Francisco area, where we can go out for a very strong cup of coffee, like Philz coffee (yum yum, and they add a mint leaf), but the usual cup of StarBucks, is not going to be as strong as say, a cup of Peets coffee, if you go out.
