Modafinil 3

After my last post, "Modafinil 2", I did take 200mg of modafinil divided into two doses throughout the day.  It did help, but the effects were not as strong as when I started modafinil, which I already explained as probably being because I was coming off of generic olanzapine which was not sedating to me thus I never experienced fatigue associated with that AP (antipsychotic).  The next day I took 1/2 of 10mg Zyprexa Zydis (I just used a knife to cut the OD [orally disintegrating] pill in half), and have been taking this 5mg of Zyprexa Zydis for 2-3 days now.  While on 5mg of Zyprexa Zydis these past few days I have been taking 100mg of modafinil upon waking and it has been allowing me to function in the day with about 10 hours of sleep per night.  Perhaps I could get up with less sleep, say 8-9 hours, but I feel quite tired in bed when waking up with that much sleep, and decide to sleep in for another 1-2 hours.  If I were to sleep for only 7-9 hours at this present time, I would be depending on modafinil to wake me up thoroughly, which it may be able to do.  As time goes on while I'm on 5mg of Zyprexa Zydis, I plan to eventually see if I can cut down my sleep and remain on 100mg of modafinil.  As I plan to resume full-time day studies in fall 2012, I may need to up the modafinil dosage to 200mg due to function on only 7-9 hours of sleep, but I'm hoping that 100mg will be sufficient.  The doctor originally prescribed that I use 200mg, however, I found that 100mg is enough so far for my purposes (part-time night student).
