Taking new meds is definitely scary. I haven't been prescribed Lithium, but I'm seeing a psychiatrist soon and I'm afraid of the meds they are most likely going to prescribe me. The only mood stabilizers I have ever been on were antidepressants, years ago, and they did me no good. I've talked to some people here about this already, including DocJohn, and he told me to take what others say about side effects with a grain of salt. It's going to be different for every person, and like the others said, if you notice any negative side effects you can switch off. There are plenty of meds out there - it's all about finding the right combination for you. Best of luck!
