Hi Frogy
If you decide to get a multi vit, go to a chemist and talk to someone who knows about vit's who can tell you about them even if you go to coles and buy it later. I found out that the multi vit I got was not as good as I thought it would be(Its a big advertised brand). Also you might get a yeast infection (which don't help matters) try and eat garlic rich food and some yogurt (I did and didn't get yeast infection )
Don't worry your not blabbing, I think I know how you feel I've been going through it (the fight with Dr's and feeling like crap) for the past year.
I agree with castle (hi castle!!) go see your Dr if you don't pick up in the next month.

take care
Chris
