I judged too fast! I feel awful now.
Just 3 h 30 min with the plug in me, and I don't smile anymore. Maybe the hot weather is guilty...
I will have some refreshment, then I will continue reporting how I feel.
Fact which doesn't help me: I drink a lot, and my body swells. My bra and belt are tighter than usual (look the picture), and this is really, really hard. But I don't give up yet.
