I have been told an edible helps a lot if you actually want to experience any type of hallucination.

If you're willing to add drugs to the mix then the tank isn't really necessary

Well I guess not. But there is a difference between taking an edible at home or socially and taking one pre deprivation tank.

Can you share a bit more about your experience using a sensory deprivation tank with sleep apnea? Did you bring a CPAP into the tank?

Not at all, I just went in like normal. I don't use CPAP at home because I've been too lazy to get it, but I know I have sleep apnea since I snore all night.

I think because you are weightless in the water my airways open up so I'm not affected in the tank.

Maybe the reason you're too "lazy" is because you're exhausted because you have sleep apnea.

Go get your CPAP. It will change your life. It will also extend your life.

This is an interesting thought experiment for my uneducated brain. How much of your body is actually "weightless" in this situation? Or is it just a trick of the mind? Surely gravity would still affect parts of your body? What difference does fully submerged vs. floating have on this effect?

It's not the same sensation as weightless. It's a lack of pressure points anywhere on the body. It's like dropping backwards into a deep snow bank. Actual weightlessness is disturbing, if you're not used to it. This is just comfortable.

snoring does not imply that you have sleep apnea! I actually had a sleep study done, I snore but have neither apnea nor dyspnea.
