Hi, IsableC! I, too, have hypersomnia and words cannot describe how difficult it makes life. I'm sure you understand. I just stumbled upon your message from back in April and was wondering if you ever purchased the Sleep Tracker you mentioned. It sounds really interesting. If you bought one, has it helped much? I have to wonder if our thyroids are part of the problem as I've often read/heard that hypothyroidism is one of the most common culprits of sluggishness, sleepiness, lethargy, etc. It can even be missed on a blood test, so some people benefit from thyroid treatment without the official diagnosis. We all need to pray for each other, that we can discover the root cause of our problem! Hope to hear back from you --
