What can I do to stop feeling so restless?

Restlessness? It depends on what is causing you to be restless. I can think of lots of possibilities. It could be physical, mental or even a combination. It could be from a thyroid problem, anxiety, low blood sugar-to name just a few. It matters how long it has been present. I would suggest starting with an evaluation from your local medical doctor and to go from there. Good luck.
