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 brings Cassio to Desdemona, and they discuss Othello's anger. Emilia speaks of irrational jealousy: But jealous souls will not be answer'd so; / They are not ever jealous for the cause, / But jealous for they are jealous: @'tis a monster, begot upon itself, born on itself. (157-160).
