Near Blackout with Hydro

[ClassicJack]

I had indulged quite a bit with Oxyfast and Vicodin/liquid hydrocodone over the last couple months, ie. 600mg of the oxy over the course of a couple weeks with significantly less hydrocodone use at about 100mg. I was extremely irresponsible with my acetaminophen intake throughout in regards to the latter, mainly because I mistook the 4000mg per day health limit as per dosage. Last night I took a 22.5mg dose of hydrocodone with 1500mg acetaminophen after 2 weeks without and had mild but notable effects as I had accumulated a tolerance quickly. After a little bit I became intensely tired which wasn't particularly odd until I noticed that my vision was very gradually fading to black. After about 5 minutes of hoping it would go away it only worsened to the point where I could see next to nothing. This was accompanied by muffled hearing and ringing in the ears. I tried to make my way down the stairs in order to be visible if I passed out but found myself so disoriented and dizzy I stumbled my way down a few steps and had to sit on the stairs. I sat there for about another 15 minutes half-deaf and essentially blind and waited for it to subside, which it eventually did. Afterward I had a lingering visual effect of blurred spirals in the peripheral vision of my right eye for about 20 minutes. My questions are: what would most likely be the cause of this? The hydro? The Apap? Etc? And is it so unusual to have such a prolonged state of near blackout? I only had the sensation once when I was young which was not associated with drugs and subsided after about a minute, I had actually thought of it as a near-death experience at the time (approximately 13 years old) and never associated it with blacking out until after this incident so it was a pretty frightening experience honestly.

This happens to me quite often due to low blood pressure, it is certainly possible that the opiates caused a drop in your blood pressure. I know that they lower mine, not significantly, but do lower it, and it is a very common side effect of opiate use. As to why this hasn't happened to you before could be because of a number of factors, any drugs you have used recently, your food intake, your water intake, ect..., but I would definitely recommend separating the acetaminophen and the hydrocodone next time you use Vicodin regardless of whether the acetaminophen was the cause of the near black out experience, or not. Just the effects it has on the liver are enough to persuade me from using Tylenol on any type of regular basis.
