  1. I was diagnosed of (HIV) in 2012 and I have tried all possible means to get cured, i even visited phonologist but all to no avail, until i saw a post in a health forum about a herbal doctor from Africa who prepare herbal medicine to cure all kind of diseases including HIV/AIDS, at first i doubted if it was real but decided to give it a try, when i contacted this herbal doctor via his email he sent me the Hiv/

    Aids herbal medicine through courier service, when i received this herbal medicine, he gave me step by instructions on how to apply it, when i applied it as instructed i was totally cured of this deadly disease within 5 days of usage, if you are suffering of this diseases you can as well Contact this great herbal doctor via his email dromohanherbalmedicine@gmail. com whatsapp now +2348164816038,

  2. yeah, I had some massive teeth problems and I used way more than directed of Ibuprofen. I think I may have destroyed my stomach (like really fricking bad) I dunno what I'm going to do. I get the worst chest pains (either ulcers or stomach sphincter problems or both) Esomeprazole ( Nexium etc) helps but it's no cure and is apparently pretty bad for your stomach too.

  3. I think I like what you're trying to do Doc but I wouldn't rag on brand names like "round up" Instead just blame the generic chemical "Glyphosate" I mean, don't get me wrong Monsanto and Roundup should be shamed. I just don't want to see a potentially good human have to deal with these Legal Monsters.
