45 yr old, Caucasian Male, 5'10", 190 lbs that went through the past 5 years of rather heavy drinking alcohol. During the last 6 months, Drinking was increased to about a liter of vodka nightly. I stopped drinking alcohol abruptly and have not had any alcohol in 5 weeks. Since that time, I have noticed an urgency to urinate several times daily and nightly that yield only about half of the normal urine as I am accustomed to. What are the possibilities that could cause this? I have diabetes and cancer in grandparents (passed). Hypoglycemia in mother and heart failure in father(passed). I drink coffee almost daily 2 to 3 cups. No dehydration or increase in thirst. No soft drinks in diet. Currently, only beverages are tea, water, milk(with cereal). Slightly overweight for my build. I ride a bike almost daily(30 mins) for work, not really to exercise. Probably not STD related (been 3 years without). When the urgency comes on it is very strong and I must relieve it within a few minutes of onset. Thank you for your time.
