more is better but 4 is fine

I've had days when I jusy wasn't interested in the lemonade and only consumed two. It's okay to have days like that, but try and drink at least the minimun the next day, in order to keep your energy up. I always feel a little weaker the next day until I've gotten 2 or 3 glasses down.

I'm glad you're feeling better. Ugh, and I know the fate of having let my senna tea get cold. I don't envy you there.

Which reminds me, time to put the kettle on. Have a great evening!
