Day two of Keto and I'm ok.. does that mean I'm messing up?

Everyone else tells of headaches, no energy, slugishness, brain fog, irrational behavior/reactions... But I have none of those. Does that mean that I am not doing it right or do I just have to wait longer to not feel well? Not that I am looking forward to it, I just assumed that would happen before me loseing fat/weight would so... not sure. Any advice?
