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.
The senate is satisfied, once Desdemona confirms that she loves Othello, but Brabantio leaves saying that Desdemona will betray Othello: Look to her, Moor, if thou hast eyes to see:/She has deceived her father, and may thee, (Act I, Sc 3). Iago, still in the room, takes note of Brabantio's remark.
