I think melatonin and (maybe) video game addiction temporarily cured my depression/anxiety. I feel the need to write a book about this. But seriously, ever since I started taking melatonin, my imagination and ability to visualize things in my head has significantly increased, and I can think clearly with no underlying anxiety as before. Not only that, but I can finally enjoy living in the moment and stop constantly thinking about what could go wrong in the future. I feel so free now, it makes me want to cry (Oh wait what am I saying? I am disgracing the INTP master race D: .) How can such a simple hormone have such drastic effects? There's probably already an article on this I haven't bothered to read. Oh well. Experience is better than reading about it.
*also, if interested, my dosages varied from 2.5 to 7.5mg of Melatonin every night for about a week.
Though I have also undergone some other changes in habit that may have contributed to my transformation... I have eaten quite a significant amount of meat and no grains at all this week, and also have stopped eating as much in general. So it really could be any of the above that has helped me. And I know I have changed for the good because I have finally regained my addiction to video games. Why is this good? Because being addicted is a billion times better than not enjoying anything at all and being bored all the time.
