I found this energizing, strong, and I feel playful and drawn into whatever I am doing...so maybe focused. I also found this to be arousing and perfect for sex. IF I am physically tired...after say 2-3 sessions with this I become sleepy. However when I am not physically tired in the first place...that tiredness can take much longer to show up. And the "tiredness" thing tends to show up after a while for me with multiple sessions with a sativa in general (thinking - stimulated to action strains eventually uses enough energy my body eventually must rest more than the strain effects make me tired). Hope this is useful!
