Drinking alcohol has a complex effect on your circulation. In moderate amounts, alcohol can cause blood vessel dilation which actually improves circulation. This is why people report feeling warmer while they are drinking. Excess drinking can cause an increase in your blood pressure, but is not specifically associated with poor circulation. Therefore, the association of your drinking with poor circulation is peculiar Nevertheless, It sounds like from your description that you may have some poor circulation in your hands and feet (from your question it sounds like you may be having some skin issues?). This is something that may need looked at. Poor circulation in the fingers is sometimes caused by something called Raynaud's phenomenon where fingers can turn blue from constriction of arterioles. It is most often associated with other conditions such as lupus or scleroderma
