I recently had dengue quite badly (hospitalised for dehydration 3x – the last time for several days after collapsing unconscious)after which I purchased dembarah, which arrived swiftly, thank you. By the time I took it, I felt I was in the “chronic stage” and would like to say a very big thank you as it worked very effectively and energy levels returned to normal, as did heart function, which had become quite strange with the least exertion, whilst in the aftermath of having the dengue. Worked exactly the way you said it would – felt like I had come down with it all over again, the first day, felt better but still pretty lousy the 2nd day. After that I just improved steadily each day. By a fortnight later I was powering through unbelievably full days with no problem at all! I can definitely recommend it, and wish all who experience this debilitating virus could be told about it, and be cured so simply and conveniently! Thank You Blue Turtle for your wonderful product and service, Gisele
