Thank you Glenn and Mrs D very much for your advice. I am very bad at drinking fluids, especially water. I find water chilled or at room temperature very difficult to take in anything other than small sips from time to time. Because of a tendency to prostatitis I drink cranberry juice which was recommended by my doctor years ago and certainly does help. What I will do from now on is dilute the cranberry juice and consume an increased amount that way. I never realised that my drugs contributed to this problem and also believe I am correct in saying that my bad cramps could be worsened by a poor fluid intake.

Thank you again


Tony
