I am a diabetic been for 32 years.. I had stage 4 head and neck cancer ..I have no thyroid was fried with all tge harsh radiation. I use Stevia when I even use it .. I kinda got use to no sugar or anything to help sweeten things .. been losing weight have no clue why ..not even trying .. I hardly can move head hurts so bad .. I lose my eye sight but, comes back. And the headache clinic told me do not use tylenol or ibuprofen too much. I havent been able to sleep for years and melatonin does not work for me. The cancer center in zion Illinois had me up to 25 mg. I do use Voltaren a lot way to much ..
