I'm having a terrible time onHCG (sublingual compounded from pharmacy). I'm on day 14, and have lost about 11 pounds, which is fine because I'm already in the normal range, but I have had terrible muscle cramps and weakness. We thought it was a combination of low sodium and low potassium, and upping that has helped, but I'm so weak that I can hardly stand in the shower and wash my hair. My pulse shoots up from my normal 60 to about 110 when I do that. Prior to HCG, I played golf, tennis and ran, and I now can hardly walk on this diet. I am under a doctor's care, have had bloodwork and EKG,but nothing shows up. I believe I should get off, but don't want to gain back the 11 pounds. I see my dr. on Tuesday, which will be 17 days, but am open to all advice. I'm going to need rehab!!
