"i started on monday taking escitalopram drops. my doctor told me to take 10 drops  (10 mg). i read the instructions and opted to take 5 drops  (5mg) as the drug was new to me and i&#039;m a very little lady and was worried about the dose. within a few hours i had the most throbbing headache that wiped me out all day. the following morning i took another 5 drops and again had a throbbing headache. i took various over the counter medicines to rid myself of this headache but nothing worked. luckily a friend popped over and i made an espresso coffee for us both. within 5 minutes of drinking the coffee my headache had disappeared completely. i was relieved and shocked that a dose of caffeine could put me back in the land of living again."
