I've done Morphine, my first opiate/opioid 3 times, Vicodin maybe 5 seperate occasions, Percocet once, and idk if tramedol counts as one or not, but if it does, maybe 7 or 8 times. These are total times in my life. I was told to be extremely caution with these drugs/meds, and respect them. No problems with them thus far. That goes to alcohol. Morphine hands down favorite. I was sober, never knew such drugs existed, back in 2006, and never dreamed they could cause such a good feeling. I remember it most, and in great detail as it was indeed my first, and the surprise when I woke the morning after. Took two at night, as I would with tylenol, went right to sleep.. And rolled the magical wave throughout most of the next day!! I hear Percocet is stronger than Vicodin, but the one time, I was well past drunk, and split it with a friend, who crushed it and we snorted it. I remember it was nice, but it was very late, and went to bed shortly after. So I guess that is second, then Vicodin.. Never had any others.
