Hi, and thanks for your medical question on eHealth's Ask a Doctor forum.
Your symptoms (tingly feeling that washes over my entire body, every move I make. Even when I’m sitting still and only moving my eyes, I still have it. It's the same feeling you get when someone scares or startles you, it’s similar to that. It only lasts a second or two, but I have them constantly, every move I make.) point more towards a whole body tremor.

It is possible to feel tremors all over the body. Tremors are often associated with drugs, alcohol, smoking, lack of sleep, stress and fatigue. In your case it is possible that smoking is the cause. Chantix can cause sleep related problems that you may not be aware of. It could also be due to having an irritable person around you so that you are always on guard. At home you can try relaxation techniques such as meditation, yoga, deep breathing exercises, listening to music etc. Keep yourself active and engaged through out the day.

The tremors can also be seen in peripheral neuropathies of diabetes, in hyperthyroidism, parasomnia, multiple sclerosis, TIAs or transient ischemic attacks or mini strokes, hypoglycemia, disorders of calcium metabolism, hyperparathyroidism etc.

Consult an internal medicine specialist or your PCP. Discuss these possibilities with your doctor. It is difficult to comment beyond this without examining. A comprehensive investigation is required keeping all the points in mind. Hope this helps. Take care!
