narcolepsy
"I was prescribed Vyvanse 50 mg for the treatment of my narcolepsy w/o cataplexy & hypersomnia. The first 2 weeks were great but I found my body quickly adjusted to this medicine making it almost completely ineffective by the end of the first month. The 2nd month, I went to 60 mg. this month, I'm on 70mg. I'm not falling asleep while driving, however I am still having episodes of extreme sleepiness and sleeping extremely deeply at times. I'm also going between sleeping 5 hours to 15 a night. My main concern is: I'm on the maximum dose so just where do I go from here?!  I also have bipolar disorder/anxiety & I've found my need for anxiety medicine to be almost nonexistent, which is a great bonus."
