hello thank you for trusting HCM dear hot flashes and flushing are common but less noticeable than other effects, such as loss of motor control and slurred speech, and are often only noticed by the person experiencing them. It may seem like nothing more than an annoying side effect, but it is the outward manifestation of the changes alcohol causes in your body.Alcohol causes hot flashes of a different sort by affecting your brain chemistry and circulatory system. please avoid alcohol.tab.benfothiamine once a day.if symptoms not improved please consult your doctor he will examine and treat you accordingly. I think I answered to your question if you have more questions feel free to ask. take care
