i need to urinate every 30mins but only when drinking e.e after having a few beers

Beer contains alcohol which is a diuretic which elevates the rate of urination. Since the rate of urination goes up your water stored in your body is loss out faster then should be and can cause dehydration.

After drinking a few beers its good to drink a lot of water before you go to bed to rehydrate yourself so you decrease the chance of a hang over in the morning.

when compared to others consuming similar amounts i visit the bathroom 3 times as frequently. Is this normal?
