I have just had Botox in bladder, help needed!?

HI i am in the UK and on fri morning i had botox injected into my bladder as i go to the loo up to 35 times a day!! It was a very painful procedure and they said it can take up to 2 weeks to feel any effact but im very impatient as i have had to live with this for a very long time. Has anyone out there had this treatment and how long did it take for you to feel it was working.
