It didn't used to happen before, started in the last few months. Is it adrenal related, insulin resistance, congested liver or something else?

If after eating this would be rebound hypoglycemia:

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.

Thanks.

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.
