That is interesting about the Apple cider Vinegar. When I was having acupuncture during IVF, my acupuncturist recommended organic ACV every day as it has great health benefits including being a gentle detoxifier for the liver which was my problem. It has to be organic though and undistilled. I had stopped taking it when I got pregnant but I think I will start again now. When I looked it up on the net, it has loads of benefits.
I have also found that taking Floradix (which is a herbal vitamin and iron tonic) has made a massive difference to my energy levels, although I was low in iron so maybe that is why.
