I've did my first flush almost 4 years about but then lapse for a couple of years. When symptoms returned 1.5 yrs ago, I started flushing again.
While my GB aches once in a while, I've never had an 'attack'. Well 5 days ago, I had one out of the blue (guess the beer, lamb chops, butter, suger, buttermilk did me in) - so went home from work - lots of MgSO4, apple/carrot juice, heating pad, etc. - the major knife stabbing pains passed after about 8 hrs.
Did a real flush last night - lots of bright green stones - only the bigger ones are in the photo - lots of other smaller ones too.
