Ideally, Flomax should be taken 30 minutes after dinner. The dramatic improvement in flow and a decrease in urinary frequency are what is to be expected with this drug. However, the difficulty starting your flow is not expected—especially if this medication is working. One possible explanation could be related to the depth of sleep that you are in prior to waking up to void. If you are not fully arousable when waking, then in theory voiding may be more difficult. A trial of a different alpha blocker may be helpful, but I would definitely discuss this with a urologist since the findings are not typical of the results usually seen.
