I would be really, really careful about who you ask for advice because if you're getting desperate you are a prime candidate to be conned and it happens to the best. Homeopaths etc are brilliant at their jobs, i.e. selling stuff that has no real evidence whatsoever to prove that it works, by using pseudo-scientific language to blind people who, through no fault of their own, know no better than to believe what they are told because a few long words were thrown in. If you have any kind of scientific education (as opposed to arts subjects) past GCSE that will have come across as incredibly patronising so I apologise, but understand that it's well meant and also that it's a blanket sentiment that I would say to anyone. The very nature of alternative medicine is that its effects are dubious, simply because if something can be shown to work effectively and consistently, it becomes normal medicine. The treatments you will be offered in Holland and Barratt for example, as opposed to prescribed drugs, will be sold on the basis that some people thought they worked at some point. By contrast, any scientific solution to an illness will have been tested scientifically, i.e. instead of looking for evidence to support the hypothesis that it works, the researchers look for any possible evidence to disprove the hypothesis. Only if the drug can be shown to work after these rigorous tests and studies can a medicine be licensed. The only "herbal" thing I could possibly recommend is anything containing a source of iodine, which is a component of the thyroxine molecule (responsible for "energy" levels) and so may help your thyroid gland to produce more of this hormone. I think Boots do a tablet which has kelp as its active ingredient. But multivitamins etc will not have any effect other than possibly as a placebo. I imagine your doctors will have tested for anaemia (and come to think about it hypothyroidism too) as well as any other obvious causes of fatigue so if standard medicine seems to have failed you, instead of turning to the snake-oil trade of alternative medicine, I am with Nina and personally would recommend both persevering with finding an official diagnosis and perhaps trying something along the lines of cognitive behavioural therapy, where at least you can get help and advice from someone with an actual medical qualification rather than a daylight robber posing as a harmless old hippie.
