Hey guys, I'm having a PH study for acid reflux (where the put a wire probe thru your nose and down into just above the stomach area) and it stays for 24 hours and is then removed. I set up the appointment for the 12TH of September, I asked the person who will be doing the procedure if it was ok for me to vape during the study. She said nobody had ever asked her this before (or even about smoking during the study) which I found a bit odd (especially the smoking). She said she would have to get back with me after speaking to the doctor who ordered the test and also she wants to contact the vendor of the device they are using to ask them as well. Was wondering if anyone here has had one of these studies done and if so, were you able to vape during the 24 hour study or were you told not to vape? I guess the question could also apply to people who smoked cigarettes or still do smoke cigarettes who have had the test done as well. Thanks!
