Thank you for all the responses. It's good to hear that others have a similar issue.

I do drink a lot of water all day long. I started cutting back on soda last year and now I'm down to maybe 1 or 2 a month as part of my attempt to lose weight. (Which hasn't really worked.) The only other thing I drink is one cup of tea in the morning after I get to work. (I don't drink coffee that often either.)

I also take my lithium in the morning with my breakfast. The label says to take it with food, so I do that.

I'm supposed to titrate up to 900 mg taking one a.m. and one noon-ish, and the last in the evening. I think it will be too much for me. I was on 1200 mg in 2010 for about a month and I couldn't handle it. From before I know 600 mg gives me tremors after a few weeks.

I'm also supposed to be taking clonezapan at night but I have been too afraid to take it. The pharmacist said it will make me sleepy at first and decrease over time. I want to take it on a night when I don't have to get up for work in the morning because I'm afraid it's going to make me sleep and I'll be too loopy to drive in the morning. I had a co-worker get arrested for DUI and child abuse because she was sort of loopy from her Xanax and had her kids in the car. She spent over a month in jail from it and lost her job. Anyway, I'm the only driver in my household so I freak out when I'm worried I'll be incapacitated.

That's the great irony, I have too much anxiety to take my anxiety medicine. But I feel it might help the evening irritation without having to increase my lithium dose.
