Your body may have developed a tolerance to Ambien. If that's the case you need to speak to your doctor to see if you can increase the dose or change to something else.
How many times a day are you taking it? Ambien has a very short half life so it could be that it's out of your system within a few hours. If that's the case you should ask your doctor if maybe you can get hold of Ambien CR so that it can stay in your system for a longer period of time

Usually, tremors could be associated with fatigue, stress, anxiety or a form of panic attack. Other possible causes of tremors could be overactive thyroid (possibility in your case), Parkinsonism disease, alcohol use, certain medications, alkalosis, and low blood sugar. Sometimes previous injury may cause pinched nerve and may be a reason of tremor but this possibility remains low. Therefore, it is quite essential to thoroughly assess the all possibilities here with the help of a doctor. Treatment will completely depend upon treating the underlying cause. Hope this helps.
You could try putting your hand in a splint, that helps for some. If it really affecting your quality of life you should speak to your doctor about it and maybe they can give you some other medication that will help
