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.
Otello's response to Iago's question about the preexisting relationship between Cassio and Desdemona is a typical love melody which would have been standard in an earlier Verdi opera, yet it lacks the passion that would typically accompany it and is cut short by Iago's interjection.
