I never was a coffee drinker, but I have given up caffenated beverages. (After a week of bad headaches, I have had maybe one headache in a few months) Really giving up caffeine when I did was so I wouldn't have to go through the withdrawal headaches if/when I'm pregnant--I figure I'll have enough on my plate then.
I also don't like diet sodas....something about the aftertaste that I don't like.
I try not to take any unnecessary medicines....if my allergies are bothering me I'll try to tough it out.
I know I'm probably over-the-top, but it's just how I am.
I've also read that one or two cups of coffee a day isn't bad. Everything in moderation!
