Yes, and for me, the major tiredness started about 2 weeks into it. Basically, I just found it easier to go to sleep earlier each night. I didn't have much fatigue during the day.
For the most part, I was happier, clearer headed, but then would occasionally have a bit of what I'd call "brain fog". That all subsided towards the end of the 2nd month.
My E was upped about 2 weeks ago, and I will hit the 3 month mark this weekend. I didn't notice any change at all from the upping of the E, and things appear to rolling along nicely.
