Lithum symptoms and conditions

Hi I started on lithium in june09 and at first I had some hand shaking but not much. I also had some muscle weakness the first few days I started but that subsided. I'm currently on 70mg 300 in the morning and 400 at bed time for most part I haven't had any trouble except mild weight gain no more the 2-5lbs and it doesn't help that I'm not so active.on the good side tho I've had all most 80% less outbursts and still getting less

so those having troubles I wish the best to you

My wife was put on Lithium about 2 years ago for only about 6 months and frankly I saw no improvement or change.
We were assured that any decrease in thyroid activity would only be temporary however despite never having any thyroid problems before she was started on 25 micrograms of thyroxine to compensate for lack of thyroid activity.It is now up to 100 micrograms with no anticipation of any improvement.
Although there seems to be no evidence of it causing permenant damage I wish now that she had never been started on it.
