I have never had normal BS even with meds until I took curalin. I have been taking curalin for 3 months, cut off all meds, and my average BS is 5.6 mmol/L. It's so good that I referred it to a friend and I received a free bottle from this program for my first successful referral. but it's not the case with the second successful referral. it is so hard to redeem the point although I changed numerous emails with Amber, calling the CS, and last time with Yael. The coupon tab simply does not exist in any checkout pages even after refreshing the page, changing the browser, and gadget to log in, as advised. I simply give up trying because there is no real solution and it is not only me who experiences this. Few members in the FB group managed by Curalife shared similar difficulty in redeeming the free bottle, i.e., the coupon tab does not exist. I am not sure if the free bottle is really applicable for every successful referral as Curalife promises or only valid once regardless number of successful referrals.
