Hey Hoping..
ya true...the doctors had told initially that upto 5% women get OHSS and .01% get the severe form...and I remember that once my hubby asked a doctor that why it happened to us..and doctor said somebody has to be there in .01% as well...quite annoying but true...

...before the treatment I had read a lot about OHSS so atleast at every step I knew that what was happening and when it was mild to moderate to severe...and instead of doctors telling me, I was telling them..

...so its always good to be updated...in my case they had used buserelin and menopur...so only option with this protocol is to trigger with HCG...and that is the culprit for OHSS..I still don't know that why in UK they are not using other protocols like Lupron etc..will find out in the next meeting with RE?...and what protocols you used with your cycles? and were the medications same in the one you got OHSS and with other cycles?
I hope you find a good and promising option for you...
the clinics you have mentioned and about Dr Sher....I have heard about them and they all have positive reviews...(heard through indiaparenting site and I think you are already there

....
Now regarding the personal experiences..we have Anjali in Malpani and I have also taken second opinion online and doctors seem to be efficient...I don't know much about other experiences of mumbai clinics...
Regarding Delhi...I am planning to go back within two-three months if nothing works here...so have started gathering info...one of my cousin sister-in-laws has seen number of doctors so will update you about any info I will get...ya regarding Gangaram hospital(somebody recommended) but I will not recommend based on my personal experience and my sister-in-law's experience...
mother and child seems to have good reviews..will find out..
