depression
"Highly rate this medicine. It's not an anti-depressant but with depression comes a lot of sleepiness which this is great for. Also the AD's often cause sleepiness. Modafinil does what it says it does. It keeps you awake/alert and combats AD induced fatigue/tiredness. I'd question if it makes you 'smarter'. For me (83kg, male, 27 YO) at 100mg it is a mild keep me awake. At 150 it's perfect. At 200mg it's stimulating, alerting and induces mild hypomania (Which is okay but I feel slightly too 'buzzed' at 200mg). No bothersome side effects experienced other than mild hypomania which is sometimes pleasant and not too alarming. NOTE - I am prone to anxiety but this did not increase anxiety levels for me. Do not take 8 hrs b4 planning on sleeping."
