anxiety
"Was originally prescribed as a shortcourse to take 2 or 3 daily to get through a really bad patch but I have found it works better to only take occasionally when I really need it. 

Provides pretty fast (within 15 mins to half hour) yet lasting (up to 3/4 hours) relief of Anxiety. Works a treat it's probably the best thing i've ever taken for Anxiety. The only criticism is it can make you feel a bit out of it and slow but it depends on the dose. I was prescribed 5mg tablets and i find that snapping them in half to have 2.5mg still works but makes me less drowsy. I adjust the dose depending on how severe the Anxiety is. 

It's a good idea to experiment when first prescribed so you know how it affects you."
