I have, but it didn't really work out. I saw two different people 3 times each (2 people in case the 2nd person had a more suitable method of doing hypnosis) but I could never get into that really relaxed/half asleep state so that the suggestions stay in your mind. Even though the hypnosis didn't work, I did feel alot better after the 1st session about my SP, but the feeling didn't last and the subsequent sessions had little or no effect. I asked both of the people why I wasn't able to be hypnotized and they both said it might be because my mind is too analytical.
But I still think you should try at least one session because it might work better for you than it did for me.
