Is Alcohol Consumption Advisable While On Diclofenac Sodium And Temazepam?

I am taking diclofenacsodium and temazepam. Both say do not drink alcohol while taking this drug. I drink sometimes 4 or 5 beers while playing golf 3 to 4 times a week. I have been on bothe meds for about 15 years. Should I be totally off of alcohol or just not drink around the time that I put the pills in my mouth. I never have understood that. I take diclofenac at 8am and 8 pm and the temazepam around 10pm. I see no side effects except for severe abdominal cramping every week or two, but I have attributed that to greasy foods which I try to avoid but eat anyway every week or two. I am 63 years old, very active, but have to get up 3 or 4 times a night taking care of a severely (total care and transfers) handicapped female. Any ideas. 30mg temazepam.
