If you re-steep the same tea bag you used for your first cup of tea, does it count as a second cup of tea (caffeine-wise)? Or is it still your first cup of tea, just extended?
That depends on the strength of the tea. Cafeine-wise, you're getting whatever steeps out of the tea twice, so you are definitely getting more of it if drink a second cup of tea. How much depends on how strong the first cup of tea was. The chemicals don't just "wash out" with the first cup of tea.
Actually, most of the caffeine comes out in the first 30 seconds of steeping.
you can Google search for "tea caffeine steep" to find a bunch of sites that say that, and I haven't found anything that says "that's an old wives' tale".
