This does sound like sleep apnea, but what is the cause of sleep apnea?
IMO, if something is wrong, I would look at parasitic infestation first and address that to see if the symptoms would go away.
It tkes a very long time, sometimes, to rid the body of ascarids. I would suggest you look up Jessesmom's posts, get on a regular antiparasite program with regular liver flushes and keep up with the dewormer until the ascaris problem is eradicated.
Also, the liver piles junk in there in layers as well as the liver has compartments that empty over time. The liver empties this junk in layers.
IMO, you still have a parasite problem.
I would stay away from hospitals. When was the last time they actually came up with an answer to anything? Even the tests that are done, like in a medical laboratory, only have 20% of accuracy most of the time. Inside information and experience.
