I've just started taking modafinil, 100mg per day for a month then I can titrate to 200mg if needed. It will be needed! 100mg, to be honest, is making no difference whatsoever. Sometimes I literally have to look at my pill caddy to see if I've even taken it that day. Otherwise, I just OD on caffeine and go to bed at around 8. Hoping more people answer, because I could use a few ideas too!
