8mg sounds far too much for a person with social anxiety
for severe mental illnesses or extreme cases as one off then yeah but maybe if you were on an I.V drip in hospital. All the doctors and psychiatrists i have seen do not prescribe anyone 8MG for generalized or social anxiety disorder.
Its different for everyone when it comes to tolerance
Most people will start with any benzo on either 0.25 or 0.5 bare in mind diazepam is 10 times less potent than Clonazepam and alprazolam and 5 times less potent than lorazepam (Ativan) so all i can advise is what i was prescribed to begin with
i started on 0.5MG three times a day followed by 0.5MG four times a day (i do not know why they did not give me the pill in 2MG form instead of four little pills) and i found that between 2-4MG of lorazepam is more than enough, much more and it does help social anxiety and it calms me right down and i am able to look at things logically
heck, on 1MG i am able to see things more realistically and do not feel as anxious
There is no real normal dose as everyone has different forms of anxiety, some are higher than others so they will need a stronger med or a higher dose.
For someone who is physically ill aswell as socially anxious may be on higher doses of benzos for the pain. My dads first wife had heart problems and was put on diazepam to calm her body down and her heart rate stabilized
Going by what u have said, i think you are doing well on the dose you are on
