Hi, Following my most recent post concerning my latest round of blood tests, I have upped my D3 and B12 intake.........easy to do without GP involvement!! But still plagued by somebody throwing the OFF switch, often for several days of weakness, lack of energy, fatigue and feeling cold. ( Temperature range consistently in the low 36 region) The switch on is as sudden as the OFF. I've also had a physical and ultrasound thyroid examination, neither indicating anything abnormal.
My question is are there any ways of upping my basic metabolism which I can do, if my GP carries on with her "it's probably a virus" stance?
