When you look at the list of 'side-effects' of drugs, the very common ones are things like a cough, nausea, vomiting, diarrhoea and rashes.
If you think about all the ways that the body uses to detox, it will be through the lungs, the skin, the mouth, the kidneys, the bowels, etc.
All drugs are 'foreign substances', and most, if not all are toxic to a greater or lesser degree. A 'side-effect' is just the body trying to tell us that it doesn't want this substance in it and wants rid.
We gaily throw this stuff down our throats with n'ery a thought, and then wonder why we are getting weird things happening.
I have found that by controlling my blood sugars with diet, I have been able to reduce my meds right down to the bare minimum (I now only take a fraction of the insulin I used to plus one Metformin, and have dumped the Byetta - that trashed my digestion big-time and the blood pressure tablets too, that were extremely toxic), and rarely, if ever get any side-effect/detox reactions at all. If I could get off the meds completely I would be in my element. I am working towards that, but the body takes time to heal, and it is early days yet.
We have a friend who has had a persistent cough for at least 5 years. I keep telling her to get off the chemical squash, but does she? Like heck. That stuff makes me cough, which is why I avoid it like the plague, so goodness knows what it is doing to her.
We weren't designed to consume chemicals or toxins, or anything that has been adulterated, modified, refined, homogenised, pasteurised, hydrolysed, hydrogenated or any other 'ised' or 'ated' you can think of. No wonder we're so sick.....
