C.S.
Definately have your friend check out RESOLVE. They have wonderful bulletin boards, filled with women who can share her struggle and offer support 24/7. Also, Pulling Down the Moon: I'd recommend joining their mind/body class ASAP. Both resources saved my sanity and were a great resource for information. I met lifelong friends in the mind/body class... and 11 out of 12 of us are now parents (in various ways). We compared notes on doctors, treatments, tests, medicines, etc.
Before I started fertility treatments, my ob/gyn told me that The invitro process also only increase your chances of pregnancy by 20%. I blocked that out completely, desperate to get pregnant. I did 4 rounds of IVF with no success. In conjunction, I changed my diet ("The Infertility Diet: Get Pregnant and Prevent Miscarriage" which involved no caffiene, no alcohol, no meat and on and on and on), did yoga, did accupuncture, took herbs, stopped taking hot baths, passed on the sushi and everything under the sun anyone, anywhere, ever said helped them. Nothing worked.
Everyone thinks that what worked for them is the best way to go. In my experience, Eastern medicine is expensive and didn't help. In the end we gave up. We started the adoption process and we got pregnant on our own. Life is mysterious... (by the way I went back to my lifestyle of too much work, exercise, drinking, and a normal diet)
The stress levels women experience during this process are astronomical... I heard from our mind/body instructor that women going through invitro have the same levels of stress as women getting cancer treatment. Remind her that she's not alone and to get support. Listen to her when she keeps being told by insensitive people: "oh, just relax."
I'd be happy to talk with her if she has questions. You're such a good friend to her... she is very lucky to have you. Hang in there!
