Narcolepsy
"Hello, I was diagnosed with narcolepsy when I was 12 years old but it was discovered during a sleep study in 2010 out at  hospital in denver colorado.  I was told I had probably had the disorder my whole life. I am 18 years old now and struggle with this disorder everyday. Provigil has helped quite a bit but does have some cons. The lack of appetite will happen anytime you go off the medicine for even a period of 4 days then go back on it. I also have built up a tolerance to the 200mg so it has started to wear off about 4 hours after taking it and is a very hard medicine to get the dosage upped on. Insurance co will fight you the whole way. Also lost a substantial amount of weight when I first started the med."
