I wouldn't go there if I were you...

The central nervous system is powered by what is essentially a wet-cell battery,
with the blood plasma electrolytes being the battery's fluid, and its relative parts per billion of trace elements like Lithium being the elements which can make a big difference in its performance. That performance among other things regulates system performance characteristics of mood swings, and responses to stimuli, and other vital characteristics, and messing around with it isn't a good idea, because even when you think you know what you're doing, it's very probable that you really don't, because it's very complex. It isn't like re-programming a computer, or re-recording a  disk, because you're also altering the systems with which you are doing all that as it is happening, and therefore your perceptiveness and points of reference are unreliable. You're trying to play the game while re-writing the rules as it progresses, which isn't the smartest thing you could be doing.
