The only thing I don't like about lithium is that it gives me a dry mouth. I spend a good part of the day thinking about drinking. I'm thirsty now. I can't even go out without taking a drink with me. Or if I don't, I have to buy a drink at my destination. I have to drink during class (which thankfully they let us do).
And because I'm always drinking, I have to think about the consequences. There has to be a toilet wherever I am going.
