For over a year 60mg ms contins (morphine sulfate) extended release, taken orally, was my DOC. First I'll say: I've seen a number of friends of various builds eat and snort them, and as one poster above pointed out, it seems to have a varied impact upon people. I'm a 140 lb. male and was 24-25 during my dalliance w/ this substance, so I'll share my summarized experience and hope it can help....
The first time I dosed I simply chewed up the pill, coating and all, and swallowed w/ water. In fact, I never removed the coating, except by chewing. I'm not sure removal will make a difference buzz-wise, but it'll probably be easier on your liver. Anyway, I felt a slight to moderate buzz after one 60mg. I probably could have waited longer than the 30 mins. after my first, but I took my second in the same manner after that amount of time. Having no tolerance to opiates this was more than I needed. I enjoyed the high thoroughly, yet I was nodding moderately, some color left my face, and my breathing became slightly shallow. If I had taken 90mgs as opposed to 120mgs I'm sure I'd of hit the sweet spot. After several uses at 90mgs I needed 120mgs to attain a satisfying buzz, and once I hit that dosage I stayed there for at least a year. I'm by no means advocating you repeat my first trial, your tolerance notwithstanding. IME, ms contin ingested orally has a long half life, and I'd often feel them for close to 20 hours, w/ a peak at around 4-5 hours in, after which it slowly wanes. Given that, you should feel comfortable dosing incrementally to be safe w/o anxiety over losing your buzz. Typically, I'd eat a 60mg, wait up to 2 hours, eat another 30mgs, wait another 1-2 hrs and take the remaining 30mgs. As I said, this faithfully satisfied me for some time, granted I stuck to weekend use as best I could.
I'm not too familiar w/ hydrocodone, yet I've heard oxys are just over twice as strong per mg as ms contins, and IME this seems right. I have no doubt you will get a buzz from oral use, and understand your frustration w/ everyone's insistence you plug them. Admittedly, I've gone that way, and they hit stronger indeed, but c'mon, you said you wanted to eat 'em very clearly implying you weren't interested in banging 'em, plugging 'em or whatever. I don't know why some people act like someone is a homophobe b/c they don't want to insert drugs in their rectums, haha. Maybe it's a joke I'm not in on.
I would start w/ no more than 30mgs and after a light yet fatty meal, wait at least 40 minutes between dosing another 15mgs (your idea to cut them in 4ths sounds good). Yeah, you may end up waiting an extra 1-1.5 hrs to get where you want, but you don't need to worry about them wearing off if you don't do a big dose initially, and you'll be safe. I'm guessing you'll need more than 60mgs to feel decent, but unlikely more than 120mgs. Again, I'm not suggesting you start at either of those doses - work up there; you can always do more; never less (cliche yes, but it's kept me alive). Good luck, and lemme know if you need me to expand or clarify any of that.
PS - I can see why these have a reputation for being underwhelming as effie stated, yet I often hear that outta individuals w/ severe heroin habits, or 180mg+ a day oxy usage. While I'm sure they don't mean harm, they're limited outlook hurts beginners. Not trying to attack anyone specific, but for the sake of safety ms contins should not be understated unless it is explicitly clear concerned individual is notably opiate tolerant.
