Like mentioned above, take the 60mgs & if it doesnt do much, wait a few hours & take another. Dont take them more than 60mgs at once if you have no tolerance. Morphine is very sedating.
I usually have a low tolerance with all opiates & it doesnt take me much to get high. My first time on Morphine, I took 50mgs figuring since alot of people on this site were saying 100mgs wasnt doing much for them & Morphine has a low BA.
Im not stupid, I know how opiates can be for one person & not the other so I took 50mgs & I was so high...........my legs felt like jello & I could hardly keep my eye lids open. It was a very sedating high for me & I enjoyed it, if you like that sort of high. I started to take 25mgs a time after that because 50mgs was too powerful. Start low & work your way up because no one knows what you can handle, not even yourself.
