narcolepsy
"I tried this off-label because I was always waking up tired and never felt rested. I took 4 mL before bed. The results were incredible. Woke up exactly 4 hours later feeling alive and not exhausted for the first time in years. I've since been diagnosed with narcolepsy so I know why this medication was so effective for me. Unfortunately I can't afford it so my only option is dexamphetamine which doesn't help me much."
