I'm naive and simple too... no idea what DHEA is!? It must do wonderfully magical things to be so pricey! I've Googled and see its a hormone?
On the subject of folic acid vs. folate, folate is the natural form of folic acid - the same form that we get from eating certain veg (e.g. lentils, asparagus, broccoli, spinach, beetroot, beans) so we know that our bodies can deal with folate. Something like 1 in 4 women can't metabolise folic acid which then means that there's an excess swimming around in the bloodstream which isn't great and means that the nutrient isn't doing its job.
Based on this, and the fact that every folic acid supplement I tried made me feel sick, I decided that I may as well take folate rather than folic acid to ensure that I was getting what I needed and absorbing it properly. There seems to be only one downside to taking folate rather than folic acid and that is the price! I choose to take Solgar folate which I think is one of the pricier brands but that is purely because they do a 1000mcg tablet and they don't use weird ingredients in the binding (lots of allergies here).
(Note that Wild Nutrition list their folate in the fertility supplements as 'folic acid' because otherwise women are concerned that the supplements don't contain 'folic acid'. It is definitely folate that is in the pills though - I checked with them).
Kwick - a short time without your supplements won't make a difference because with the vast majority of them we build up stores so your body probably won't notice most of the missing pills. Sorry that you're having such a busy time and the hassle with getting the DHEA. You'll somehow manage your IUI - it always amazes me with all your travel that you manage to get your scans etc. done. You are a very determined lady!
Hope everyone's ok this evening. I am so tired and quite miserable but I'm assuming its hormones so not unduly worried, just a bit fed up!
