"I have had fatigue and brain fog for years now, so I decided to try modafinil. I took 100mg on my first day at 7:00am, by 8:00 I could feel my tiredness diminishing and went to work. It certainly gave me more motivation and focus but at the same time you feel slightly weird. 

You certainly know you have taken a drug and for me the slightly wired feeling is a little off putting. People leave comments claiming it's amazing etc but I feel people taking modafinil for the first time should take caution.

On 100mg It was incredibly hard to sleep, my mind started cobbling together thought after thought of random things, anything but shutting down to sleep. I would recommended starting on 50mg, for me 100mg is too strong."
