My torso also gets very hot after defecating sometimes. I take it that's due to a congested liver?
I do not have any ideas on that.
Since taking artichoke powder I'm also getting shoulder blade pain on both sides randomly. Is this a liver detox symptom?
Sounds like the gallbladder. If there are stones and/or inflammation then the contractions the artichoke will cause could set off a gallbladder attack. Supplementing with lecithin granules can help as well as the artichoke given some time.
Sometimes after eating a meal I just go to bed for an hour or so.
PS: Does sex lower cortisol or increase it?
Normally it should decrease it since sex can be relaxing. If the intercourse is painful or otherwise stressful this would raise cortisol.
