How do you stop tremors?

Based on causation: At your age, you could possess a benign familial hereditary tremor or perhaps a thyroid issue. The latter handled by thyroid meds, the former with meds to control the tremor, such as aprazolam, benzodiazapines, primidone, etc.

No cure: If a cause of tremors can be determined then treat the cause. Otherwise medications can often control the tremors if they are essential or familial tremors.
