How many 10mg's have you been prescribed and how often are you intending to use it?
As a first time user, 10mg is a very high dose, that'd knock out most first time users.
Tolerance with valium and all other benzo's is a big issue. For me personally, I was dose doubling every week to get the same effect.
So it was like
Week 1: 5mg
Week 2: 10mg
Week 3: 20mg
Week 4: 40mg
So within 4 weeks I was taking 280mg per week which is quite a lot to be honest. I then ran out of it and went cold turkey. After 2 days I went back to the doctor and explained what happened, it took me 2 ½ months to ween off of it properly, I really got myself in a sticky situation.
I now use betablockers (40mg Propranolol) much more, because there are no issues with tolerance. They don't work a tenth as well with the mental side of my anxiety. Though they do reduce the physiological signs such as fast heart race, shaky hands, jittery etc...
I don't know too much about social phobia so I can't be of much more help. I do take 300mg Venlafaxine and 150mg Pregabalin to help with my anxiety as well as my depression. Both of which have no tolerance or addiction issue, but they do have HUGE dependency issues. I decided in January to come off of Pregabalin and the withdrawal effects were horrible, it took me 3 months to be fully clean but the anxiety was too much so I had no option other than to go on it again.
May I ask what SSRI's/SNRI's you have used in the past and what dose?
And are you taking either at the moment? And what betablocker are you taking at what dose?
