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.
Shakespeare in Love is set in late Elizabethan England (the queen, played as a young woman by Cate Blanchett in Elizabeth, is played as an old one here by Judi Dench). Theater in London is booming--when the theaters aren't closed, that is, by plague warnings or bad debts.
