hiya , i had mine done at srh on thursday . i was asked which i preffered, i opted for the spray and was told if i found it too much they would give me the injection also, however although it wasnt nice i managed with just spray onl takes 5 mins and its over with, also if u have the seation he said i would have to sit around for hour before he would discuss outcome, so i think if you can stand 5 mins of discomfort its best way, they talk to you all way through, relaxing ya, i thought of all the good things that is going to happen once all these tests and op is over, focused and it went over quick.so i hoep this helps you a little. xx
