I have been using the rasp ketones for about a month. I have lost weight BUT I am also experiencing worsening fibromyalgia symptoms (neck pain, hand pain, jaw pain and headaches). Nothing much has changed in my life except taking these diet supplements and I'm wondering if they are actually causing me to feel poorly. Prior to taking these I felt that eating properly (wheat free, high protein and lots of raw veg) was helping me a lot. I also exercise (bike or walk) at least three times per week and have gradually increased so I can manage an hour at a time. Once taking the supplements I kept eating the same things but began to skip meals where before I'd feel a real low if I did so. My pain has increased so much that I'm now scared to exercise as normal for fear of increasing pain. I wonder if not being able to properly digest protein or not getting enough protein has inhibited my body's ability to repair muscles and beat fibro. I am going to stop taking them. Would be interested to hear others thoughts on this. They appear to be widely advertised as great for fibro sufferers. Now I'm not so sure.
