Reglan vs Botox

Hi,

I was diagnosed in April 2010 with gastroparesis (unknown cause) by a gastroenterologist.  At that time, he put me on Omeprazole and Sucrafate.  Luckily for me, my symptoms have been mainly hearburn with inconsistent relief from the medications.  I met with him yesterday for a follow-up and he'd like to try something more substantial to help with the stomach emptying.  He suggested either  a low dose of Reglan or Botox to the nerve.  Needless to say I've read only terrible side effects for the Reglan, but I don't want to have an endoscopy every 6 months.  My doctor has assured me that of his patients on Reglan 90% have had minimal to no side effects, but I'm still worried.  The decision is mine to make, but I'm not sure which way to go.  Any advice you can offer would be very helpful.  thank yo!
