yerba mate of weed, lovely if you need a daily smoke or just get stuff to be done, was helpful with attention deficit.
energizing effects may feel like it doesn't work but if you don't need to feel stoned it's greate.
Somehow, it helps me with focus but it's a bit hard for my short memory, more then usual I have problem with find a proper word or some fact from the past.
and it's smells like a summer pomelo.
