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.
Othello sees this, and Iago convinces him that Cassio has received the handkerchief from Desdemona. Enraged and hurt, Othello resolves to kill his wife and asks Iago to kill Cassio. Othello proceeds to make Desdemona's life miserable, hitting her in front of visiting Venetian nobles.
