Can't speak about giggly and happy as that doesn't happen to me anymore very often. It is great for getting going and focused on tasks then makes me tired and ready for a nice nap, or a cup of coffee if I want to keep going and start over. Great daytime high.
I need to calm down and relax so I can focus on my agenda. This strain never lets me down. It also lets me sleep through the night. It will follow your mood and enhance it, so just be aware.
