Have been suffering for 10 years w. CFS, and chronic sinusitis. Been tested, poked and prodded, taken all the vitamins, supplements, ate organic, exercised and nothing helped. Started taking HCL, one tablet w. meals on Friday, today is Wednesday and I am up to seven tablets and still no warming of the stomach. My Hypochloridia must be really, really bad. Already feeling a little better. Eating less but feeling stronger, no more bloating, idigesstion or nausea. Looking forward to regaining my health after 10 years of utter misery.
