My fiance had your sympotms for about 6 months. He swore he had the West Nile Virus but they told him it was borderline pneumonia. They kept giving him antibiotics and cough medicne but neither really helped. The only thing that did help was the last time he went they put him on Cipro for 14 days. He got much better but was still very sluggish. He said he felt like a jelly fish.
When he went back for his follow up after the 14 days of Cipro the dcotor put him on prescritpion vitamins. He was back to normal in a few days. He said the vitamins made him a bit ill to the tummy until he got use to them. He takes them at night after his last meal. He takes them at night so that no caffine or other things will wash them out of his body. Caffine can destroy some vitamins and since your body heals while you are sleeping he is getting more benefits taking them at night.
