It is common, your stomach is under stress due to the dying off of toxins and microbs. Drink a alot of water, even if you throw up its still eliminating gunk.
You should not do detox of sorts unless you have time. Ive been detoxing with apple cider vinegar, I didnt really consider detox symptoms until today. I figured it wouldnt be that bad. Its pretty exhausting..
When detoxing our bodies are healing. A detox bath may help you feel better.. It will make you tired, so do it before bed. And my 2cents is let your body adjust a bit before going on to more mms.
