Thank you for the additional information.
There are many different possible causes of increased frequency of urination. In a man of your age, the most common cause would be an infection of the male genital tract, such as prostatitis or urethritis. An infection of the urinary tract, either of the bladder or kidney, are possible, but are much less common in men than in women.
There are some other possible causes of increased urinary frequency. Tumors are a possible cause, but would be extremely unlikely in someone of your age. Kidney or bladder stones can cause increased urinary frequency. There can be a chronic condition in which the bladder is irritated, referred to as interstitial cystitis. There also can be systemic
conditions that can cause frequent urination, such as diabetes. Alcohol has a diuretic effect, so can contribute to frequent urination, but since the symptoms have persisted after stopping alcohol intake, this is less of a concern.
The Levaquin is a good antibiotic, but there is no antibiotic that works 100% of the time. In particular, prostatitis can sometimes be very difficult to treat and may require prolonged treatment with antibiotics. Since the antibiotic has not worked, it is necessary to perform an appropriate evaluation to determine the exact cause.
