I've noticed over the years that almost any pharmaceutical I take causes me to break out, usually withing a few days. This is especially true of stimulant meds.
I notice some people take a lot of meds yet look very healthy. I've known girls who live off vodka, cigarettes and klonopin and eat SAD diet but basically look like supermodels.
I know eventually it will catch up with them I am not trying to justify but it is clear some people have genetically superior detoxification mechanisms.
I wonder if I have MTHFR genetic defect that impairs detoxification. Otherwise I wonder which organ is most likely the weak link.
