One event of urination at night is considered normal. Frequent urination of up to 3 times is associated with daytime tiredness and excessive intake of fluid. The difficulty is typically resolved after getting proper rest and reducing fluid intake. People with a severe case of frequent urination at night can wake up to 10 times to empty to their bladder.
