I have not heard of it. If it is just floating in warm water a cheaper version would be to float in the deep end of a pool with a noodle or two. Some physical therapy places will let you use their pool for much less than a gym membership that has a pool.

So , what is a flotation tank ?

they say its good for fibro/c.f.s/i.b.s/muscles

from this thursday i am having 1 hour for a week for 3 weeks...if i gets lots out of it i will be sure to let all know..i know how bad fibro can get..and if i can help someone i will..

Interesting. Let us know how it works for you. I wonder what the cost is?

They were talking about external stimuli , so in addition to that us fibro folks also have the internal pain signals to the brain and the part of the nervous system that is in overdrive - the fight or flight part. So between all that the hamsters in my head (as Leo says) are very busy.
I have difficulties relaxing my brain, but I don't give up. : )

here in australia..some do a deal 3 x 1 hour floats for $120...1 each week..they say the first will make you sleep sound...i hope i get something out of it..i am done waking each feeling done with c.f...this is with me 24 hours

I hope you get relief from the treatments.

I've been wanting to try this. I'll look forward to your report.

Sounds fascinating and relaxing. Best of luck!
