I quit smoking almost 3 years but the withdrawals still occur.often make a medical check up and all clear.any idea to get back to normal again?

Congratulations on: becoming smoke free! The urges you have may be a way of distracting you from the bloating and dizziness you mention. Stay w/doc until they are resolved. Smoking and coffee drinking can be psychological permissions to be "off duty." Try to replace the urges w/a health choice such as chewing sugar free gum, drinking water, or practicing a brief meditation technique - Relaxation Response by Benson
