Hi everyone! I am new to this site and not sure if my last post posted, as I cannot see it anywhere. I am in desperate need of advice! A couple years ago the doctor put me on oxycodone and hydrocodone for endometriosis. I have finally had my surgery and June 28th I quit all the pain meds for good! I wouldn't say I was an addict but definitely physically tolerant! So unfortunately that meant the dreaded awful nightmare of withdrawals! My question is now this... I need to get an upper endoscopy for some pretty bad abdominal problems I have been having and I will be required to have fentanyl administered. How long do you need to wait after stopping opioids before needing to have them again without having to go through those awful withdrawals again? As I said, the last time I had any was June 28th which was about three and a half months ago. I'm really scared to go in and have this procedure done because even though only one use I do not want to go through withdrawals again! Or has it been long enough where I have kind of reset myself?
