The effectiveness of modafinil definitely tapered off for me over a month and a half of daily use. I only ever used 200mg in the morning. It still keeps you awake if you are missing out on sleep, but the high focus and mood boosting properties will be almost completely gone. Pretty comparable to caffeine in terms of tolerance. At first caffeine gives you a boost, but after continued use you just feel barely above baseline. Despite all of that, even after tolerance developed the modafinil still kept me up at night if I took it too late, and still caused a loss of appetite. My doctor gave me the okay to increase the dose to 400mg/day but I don't even like using it anymore. I don't feel like myself on it.
It's been said quite a bit on here, but I'll just repeat that it seems modafinil is best used on an as needed basis. If you happen to need it daily I would start looking for an alternative.
I have the "brain fog" also when I don't use stimulants. I probably have undiagnosed ADD, but I don't even want to go down the amphetamine path. Buproprion seems to be helping somewhat.
