Botox Injections placed near and/or around the Pyloric Sphincter.

Hi everyone! I'm really new to this forum and I wanted to see if anyone has ever received Botox injections in their stomach to treat Gastroperisis and Vagus Nerve Dysfunction? I just wanted to know if it's been effective more times than not. I understand everyone is different but if it worked for you or someone you knew what is the "normal" frequency of these injections, experience day of and through the procedure, any side effects experienced. My GI specialist told me that if after the first round of Botox injections don't work, they were not going to work and even though I'm not really a candidate for the gastric pacemaker, if I wanted I could then go see another specialist to discuss that treatment. All I know is I'm so tired of chasing my tail with all these symptoms that seemed to be more unmanaged than managed. I have a long story, if you have any questions please feel free to ask. Thank you for your responses!
