Luckily, my caffeine-deprivation headaches are just a standard tension headache/possible lead-in to mild migraine for me. But then I have ADD and caffeine has nearly zero effect on my energy levels, etc. It helps me focus my attention a bit better I think.
Shakespeare's most striking departure from Cinthio is the manner of his heroine's death. In Shakespeare, Othello suffocates Desdemona, but in Cinthio, the Moor commissions the Ensign to bludgeon his wife to death with a sand-filled stocking.
After being deployed to Cyprus, Othello is manipulated by his Ancient (pronounced Ensign) Iago into believing Desdemona is an adulteress. Othello murders her and, upon discovering Iago's deceit, kills himself.
