As to the slow urination - could your prostate possibly be enlarged? Very common among guys your age.
From what I've read about this, I recommend you stop drinking grapefruit juice until you are NOT TAKING any of those medications at all. There is not enough known at this point, to say it's safe to continue drinking the grapefruit juice.
Check out the book "DEADLY DRUG INTERACTIONS", The People's Pharmacy Guide, by Joe Graedon and Teresa Graedon, PhD. I have the 1997 edition, and there's a more recent one too. This book discusses the problems of grapefruit juice causing dangerous effects when mixed with certain meds, even when the juice is drunk hours later than the meds are taken!! The effects can be deadly.
Err on the side of caution, would be my advice. If you ever get to the point that you are able to treat your medical conditions holisticly, and successfully, then you could resume drinking grapefruit juice. (no meds to interact with the grapefruit juice).
Good luck to you!
Sincerely,
Concerned lady
