It would be worth a 3km trek to sink weary limbs into hot sulphur. We paid $80 for a plush cabin for a week, which was such a good deal we overstayed ridiculously. I think it’s worth checking their prices and getting out of town centres a bit. It’s off season, so maybe cheaper.

There are also public spa pools at Mount Manganui, as I recall.

Mama says take Nat Mur (homeopathic) for the twiching eye. Possibly a salt deficiency.
I say stop drinking coffee (if you’ve started) and get more sleep.
