Herbex Weight-loss Formula Appetite Control 90 Tablets, expensive but not effective.

Two weeks ago , I purchased the Herbex Weight-loss Formula Appetite Control 90 Tablets at Clicks for R186.99. I honestly have to state that i have been using this formula and have followed the required Adult dosage: 1 tablet 3 times a day , 30 minutes before meals, with a glass of water. I honestly have not experienced any changes as far as my appetite is concerned. or am I from another species , does this product only applies to certain individuals, if so , then why is it not highlighted anywhere, The product is not effective and I have wasted almost R200.00, that I could have used towards something valuable.
