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.
Iago tells Othello that he has heard Cassio talk about Desdemona. This leads into Othello's tragic flaws, which are jealousy, no being able to tell his friends from his enemies, and trusts everyone. Iago and Cassio discuss Bianca and how Cassio is going out with her. Othello overhears the conversation and believes it is about Desdemona. Iago and Othello create a murder plan to kill Cassio and to strangle Desdemona. Lodovico is introduced and he is surprised by Othello's attitude towards Desdemona.
