I just started using the Herbalife program this past fri, June 10 - shakes, thermogenic supplements, and thermogenic tea. Since the 1st day I have been having severe headaches, stiff-swollen neck and shoulders, nasal and head congestion , hypertension , pain in my right arm, dizziness , red splotches on my neck and chest, flushed cheeks , and heart palpitations enough to scare me into stopping the program cz I felt like I wz gonna pass out. So I stopped completely using all the products on the evening of day 3, which wz sunday. Just as of today I am no longer feeling those reactions. Just stomach discomfort remains, along with stiff neck and shoulders. Swelling has subsided a good amount. I wz told by my personal Herbalife rep that my body isn t used to caffeine and I just need to stick with the program and trust me, it will pass . Well, I have caffeine everyday and have never experienced anything like this b4 and never want to again. So I will cease to use the products if they are the reason my body is reacting so adversely. Is there a possibility I am allergic to any of the ingredients in the shakes (which is all food so I wz also told that I can t be allergic to all natural food nutrients due to them being all natural ) or the thermogenics or the supplements? I am 39 yrs old and have good health- nonsmoker, take no medications except for OTC Allegra for the indoor/outdoor common allergies, and I only drink alcohol occasionally. The only vitamin I ve found that I m sensitive to is iron. I have allergies to decongestants and kiwi fruit. They both give me the reactions I just recently experienced with the Herballfe products except this time it wz much more alarming. I m not bashing the Herbalife company. A lot of their customers have great success using their products. I m concerned that it just might not be right for me??
