Hour-long sessions at Newcastle Float Centre cost $55.
THERE is a point in pregnancy when rolling over in bed becomes more of an eight-point-turn than anything resembling a smooth manoeuvre.
Ankles and calves can swell and merge into "cankles", the back can ache, and one feels much heavier with each new day.
So the promise of feeling weightless - even for a short time - while enjoying the benefits of float therapy sounded particularly appealing to this mother-to-be.
There is a moment of hesitation when I spot the flotation tank I'll be bobbing around in for an hour.
It looks like something out of a sci-fi movie, and the idea of lying inside the tank, in highly salted water, in the dark, freaks me out a little.
Sensing my alarm, Jason Wallace, owner of Newcastle Float Centre in Charlestown, allays my fears by assuring me I am in charge of opening and closing the tank door. And that there is a light inside should I need it.
But ideally, the darker it is the more I'll be able to zone out from the world and get the most benefit from the meditative experience.
Traditionally one enters a flotation tank - also known as an isolation or sensory-deprivation tank - wearing nothing but a smile, so I'm left to my own devices to shower and float.
Soft music plays as I lie down in the water, filled with 350 kilograms of Epsom salts, and close the door.
It takes a few minutes for me to let go of my internal to-do list. But once I do, I feel my body slackening.
My joints seem to sigh with relief as the tepid salty water takes the full weight of my body, which can now relax into its most natural form.
Gravity doesn't live here any more.
I roll over to spend much of the hour lying belly down in the prone position - chin cupped in hands, elbows resting on the tank floor. A bout of enthusiastic kicking from the baby reminds me I'm not really alone.
Many people suffering pain or stress, or those seeking recovery from a tough workout or injury find relief in the tank. I can understand why.
Afterwards, I feel relaxed and rejuvenated. My mind is clearer and I'm ready to take on the day.
