There are Nutrients that help with the production of Dopamine and Saratonin, which make you happy. Most illegal street drugs and prescription drugs that alter your mood into a happier one do so by causing your body to release it's supply of Dopamine and/or Saratonin... personally I don't think drugs, prescription or otherwise, are very good for you for a lot of reasons...

Here's a website with the list of 10 nutrients to help make you happy.
http://greatist.com/happiness/nutrients-boost-mood

And here's what I made using that list
Orange Juice [not from concentrate and organic, but it would still work if it was the mutated non organic oranges or oj from concentrate... just not as well], Spinach, and "silk" brand Almond milk thrown in the blender. Then a potato. Not the most delicious drink. But this ends up giving you all ten nutrients from that list.

I suggest researching the list and making up your own combinations.

only 4 hours after trying this I felt noticeably better. it's been 3 weeks and i feel fucking happy as shit now.
