Anesthesia
"I can&#039;t take Versed, and this is a great alternative for me for colonoscopies and endoscopies.  I have pain at the injection site (I.V) but that only lasts a few seconds until I&#039;m unconscious.  I&#039;m alert but sleepy the rest of the day, and usually take a four hour nap after the procedures.  No side effects otherwise."
