I’ve been on Modafinil since about 2005. I started off on 100mg first thing in the morning. I found it absolutely brilliant. It really helped my fatigue. After a while though I was starting to lag during the afternoons and my dose was then upped to 100mg first thing and another 100mg about mid-day. Again, this was a Godsend, and I was managing to get right through the day quite easily.
I am now on 200mg first thing and 200mg around mid-day. I must admit that I am not finding it as effective now, I usually have to take to my bed during the afternoon for a few hours, and to be honest, I could sleep all day long and all night if allowed lol. I know that it is still helping a bit because on the odd occasion when I’ve not taken it, I’ve not been able to function at all.
I wish you well with it.
