I have been thinking of paying to have them too.The cost near me is £40 minimum so it sounds like you got a bargain IF they had made a difference!
I have read that if you have excess B12 intake it won't do any harm as it will be flushed away by your body but of course that does mean you have flushed money down the toilet pan.
Why have them if your levels aren't low? If they are then you don't need to pay for them, they are free on the NHS?? I advise you to get them checked first if feeling tired, but you don't have to spend money on them!
