Modafinil 5

I have been taking 200mg of modafinil for about a week now because on 100mg I was still sleeping excessively (i.e. 11-13 hours).  My sleep time on 200mg is now about 13-14 hours, so I am not really experiencing much decrease in sleep time as compared to my sleep time before using modafinil (prior to modafinil I was sleeping 13-14 hours, usually 14).  However, I do feel that when I am awake, on the modafinil, I am perhaps less tired than without the modafinil.
