The block is not a big deal. A couple I had, they gave me sedation. The last one I had no sedation. I have a high tolerance for pain. I guess having all this pain for so long, you get used to it. LoL. All kidding aside, they told me if I don't take sedation, its better. But again, everyone is so different. Either way, it's not a bi procedure, so don't sweat it.
Please go out to the FB page. It was definitely worth it. You will never find a website with all this information. I suggest you go into it with a open mind. Everyone is different. Good Luck.. you can private message me thru Facebook Messenger if you like. Many of use keep in touch. Stay Positive!
