obstructive sleep apnea/hypopnea syndrome
"This stuff is absolutely amazing! I have never felt better in my entire life. I have struggled with fatigue, daytime sleepiness, and depression for the better part of my 62 years. I was constantly tired and always in need of a nap. I could not read a book or watch tv without nodding off. Now I am awake and focused all day long. It is like 5 cups of coffe with absolutely no jitter or side effects. I no longer take or need a nap during the day and my sleep pattern has improved greatly. I used to sleep less than 4 to 5 hours a night. I would wake up at 2 or 3. Now I am sleeping about 6+ hrs. The depression I have endured for 50 years is gone!  My wife cannot believe how much this drug has helped me. It is so wonderful to be enjoying life."
