Hi, Mark.

Nutrient deficiencies often cause problems like those eventually, even if a person does not smoke or drink. But if you smoke, you are at additional risk for that reason.

If you drink a whole lot and have done so for a long time, that is another big risk factor. If not, it is not.

Smoking alone depletes some usable B12. Other B vitamins can be interfered with by either.

If I were you, I would do a lot of reading on the vitamin forum here. I would concentrate first on B12 and B complex, and antioxidants. Regardless of what is happening to you, taking care of this issue will help you some, but it might be at the root of the problems.

If you can't stop smoking, you can still help yourself with nutrients.
