How much Ativan to take for a flight?

Hello, I am traveling to Italy next week, and being a nervous flyer, I asked my doctor for something to help me sleep and relax. She gave me ten 0.5mg tablets of generic Ativan.
I took one last night just to see how it will effect me, and to my surprise it didn't do a thing. I'm guessing one pill of that amount wasn't enough. I have read online that some people take 1 or 2+ milligrams to fall asleep.
Does anyone know how much I should take?How much Ativan to take for a flight?
It's actually dangerous to ask strangers for dosage advice. We don't know you, your body, or how you respond to medications. Best to call your doctor's office or ask your pharmacist.
Have a super flight!
Ask her, since she was the prescriber.
Take how ever much you were prescribed. Don't take more than that, to prevent overdose (Symptoms of a Ativan overdose include sleepiness, dizziness, confusion, a slow heart beat, difficulty breathing, difficulty walking and talking, an appearance of being drunk, and unconsciousness).
Ativan is used to relieve anxiety, nervousness, and tension associated with anxiety disorders. It is also used to treat certain types of seizure disorders and to relieve insomnia (induce sleep).
It is supposed to calm you down so that you can relax and makes it easier for you to fall asleep.
Taking just one pill, you wont feel the affect right away. Stick with the prescription. It should work.
If you are a regular user of tranquillisers or sleeping pills (prescription ones), you may be tolerant to the sedative effect of these types of drugs. You should have felt something but i guess everyone is different.
