blimey I didn't know Dicloflenac made you retain water. I am guessing you have joint ache or bad back if your taking that and co-codomol.? I did slimming world and I ate dueretic foods like celery, lettuce etc. Other than drinking lots of water I don't really know. I saw my doc the other day as I haven't seen my ankles for about 18 years as I retain water and all she said was to drink plenty of water and put my feet up. Not very helpful when I have a 4 month old baby an am trying to walk to keep fit. Viscious circle really.
