The reason there is not a "clear answer" is due to the nature of benzodiazepine drugs. They can become physically addictive in a short span of time (as little as 4 weeks), where you actually need the drug in order to feel "normal".
It may seem like OnePerfectOne may have gone a bit overboard with her original response, however, you are asking for medical advice online, from people who are not medical professionals. Because of that, it is in our & your best interest for answers to err on the side of caution.
For people who do have a physcial addiction to the drug, and especially those who have been on it long-term, bezodiazepine withdrawal can have serious side effects, including seizures.

That being said, given the short time span you have been on the medication, and the low dose that you are taking, chances are you will have mild side effects, such as headache or nausea. Some people are very sensitive to the drug, and as it leaves the system, have side effects, and thus need to taper their dosage very slowly.
(I know a pharmacist who took an antidepressant that needed to actually open the capsules & take part of the powder contained for a couple of weeks. I took the same medication & stopped cold turkey (by accident) with no symptoms.)
It may seem confusing, but the advice you have been given by the pharmacists & your nurse is sound, and appropriate for your situation. You can stop taking it, or you can taper the dosage. Tapering can be done either by breaking the pill into a smaller dose (you may need a pill splicer to do this, available @ the pharmacy) or by taking the dose every other day, every 2 days, etc. It will be based on how -you- feel.
Here are a couple of helpful articles regarding this classification of drug, how to wean off, & what to expect.

My personal advice - if you did not have significant issues from reducing your dose by 1/2 the past 2 days, then you likely will not have a problem weaning off the medication. Try skipping your dose tomorrow, chances are you will feel fine. You can then decide to skip it the next day as well, or take a dose if you do not feel "right", & do an every-other-day dose for 2-3 pills. If you have anything more significant than a headache, anxiety or nausea, contact your doctor & pharmacist.
Having been on anti-anxiety & anti-depression in the past, I know that all the information & seemingly contradictory information can be frustrating. Take a deep breath & try not to stress out over all the "what-ifs". T. =-)
