Hi, Thanks for using the HCM. I am happy to address your questions, herbalife is usually well tolerated but still it is wise to take under supervision of your doctor because it is usually to maintain calories and one maybe having underlying renal failure,diabetes,heart diseases, and other metabolic disorders. If you experience bloating, try changing the portion size to reduce this feeling. Enjoy healthy snacks during the day and smaller meals to assist your digestion. If you are using Cell-U-Loss, try discontinuing it and see if that reduces your symptoms of acidity. If so, then Cell-U-Loss is not for you. If acidity persists when you are not taking it, there is some other cause. Cell-U-Loss contains 3 ingredients which may be causing the acidity like Apple Cider Vinegar, Vitamin C and Iron. It also contains herbs that have diuretic properties such as couch grass and corn silk extract. Some people report that their mouth is dry like thrush after black or fruit tea. Detox products often produce thirst so you can try increasing your intake of water. Dryness from using the shakes can be caused by acid reflux since it contains guar gum and psyllium husk. These have expanding properties, which can cause reflux. Guar bean is high in protein and oil and guar gum is used worldwide in many beverages, foods and supplements. In significant quantities, guar gum dehydrates the body and can cause some serious side effects. If it is affecting you then will recommend you show to your clinician. Hope I have answered your query. If you have any further questions I will be happy to help. Thanks
