If it is diazepam, it will likely help you at 2.5 or 5mg, but I would try other things first or get them through a GP - at least then you'll know they are 'legit'. Why not have a few cups of chamomile tea and see if that helps? It hits the same receptors as diazepam (gaba) - and has no side effects. Sure it won't be as potent but it just might take the edge off.
