Hi BB !
I gave up on Contiflo as, like you, it made me feel unwell and nauseous and within 3-4 days I was back to normal.
You mentioned Urostemol, well I tried that and it did not seem to make a great deal of difference to frequency so I also had a run with the stuff from Holland and Barrett which seemed to have a small beneficial effect so I may go back to that. I guess you have to give any of these 'remedies' a suitable period of time to achieve some benefit and not expect immediate results - one thing is for sure, Contiflo is in the bin having looked at the manufacturers list of side effects almost all of which were not mentioned by my GP.
I think the reduced caffeine plan works well but I will have to make more effort with the bacon butty and brown sauce remedy !
Hope things settle down for you
All the best
Beamer
