My mrs was really bad before christmas , doc gave her anti-biotics and whatnot but she felt drained to the point of exhaustion . Doc told her to get herself a bottle of Metatone while she was at the chemist . Apparently they sell it in tesco's and asda and whatnot aswell . From what shes told me about it i've been wanting a bottle myself ever since , its just a booster tonic but from what the mrs says a spoon full could put Elvis back in business !
Hope this helps .
