No fizzies for me. I gave soda up for Lent a long, long time ago (I think I was 15) and couldn't make myself drink it again afterward.
I will occasionally have plain seltzer with a wedge of lemon.
I don't have "resolutions," but I have a couple of plans I'm trying to put in place for this year. First, I have a bike trainer (a sort of stand you set the rear wheel of a bike into to use it indoors) and I haven't used it much. I plan to bring it to work and use it while I'm checking email and MR.
Next, I haven't been to yoga class for a long time. I'd like to start going again. I think it would be good for me both physically and mentally. But I get stressed out going to large rooms filled with strangers moving around (even doing something slow like yoga) so that's a bit more of a struggle than just setting up the bike trainer in my office.
Maybe I should get a yoga dvd and try it at home or something. Or even during my lunch break at work. (I have more privacy at work than at home.)
Other than that, I think trying to earn a doctorate while working full time is enough of a goal for anyone, but I do have some wistful hopes of getting some more manga pages done soon.
