When I have had issue of wanting to swallow the oil, whichever one I use, due to just being in my mouth, I either, stop swishing, to catch my breath, perse OR put my head forward to my chin. In that way, the oil is at the front of my mouth and I can swallow and not swallow ANY thing into my throat. As for how long, I usually only pull for 20 minutes at a time YET I have done a couple pullings in one sitting. So, I pull for 20 minutes, spit, rinse and then repeat. Not sure if that is how others are pulling for 45 minutes, but it seems likely.
Great to hear your results are good!...zits are your body's way of releasing what no longer serves you, as sleeping is your body's way of 'catching up'...a good thing!...(albiet inconvenient when Life is calling!). Not sure about prostate but possibly a 'detox' symptom.
