"I have changed my mind about side effects of statins and i now feel that they have been exaggerated."
I tend to think that they are under-reported. I know (directly or indirectly) many people who've suffered pretty severe side-effects of varying kinds. The common factor in most of these cases is that the GP has been unwilling to record them.
Just as one example, my MIL was prescribed statins, and suffered limb pain and night terrors. She told her doctor, who prescribed a different one, with essentially the same side-effects. The GP refused to listen to her complaints, so she simply stopped taking them, researched other methods of improving her cholesterol, and managed to improve it by diet and exercise. The doctor still prescribes the statins, which are delivered automatically to her.
The winners are:
My MIL, who has lowered her own cholesterol
The drug companies, who (thanks to the stubbornness of her GP) are selling the drugs.
The losers are:
The NHS, who are paying for drugs that are not needed or used
The Truth: She's given up trying to convince the GP that she doesn't need or want them. He's convinced that she is taking them, and that her improved cholesterol is a as a result of this.
