I did 10 cycles with OE and the 11th with DE which was the successful cycle.
I didn't find out about my immune issues until after 9 cycles.
All immune treatment here is private as well. I have a reproductive immunoligist who manages my immune issues separately from my OB, who is fine with it, he is one of a few who believe in immune issues.
I know what you mean by getting off the drug train as its doing my head in at the moment. The break will do your body and soul good so look after yourself and do some fun things for a while without having to run to a schedule.
