So I tried
Morphine for the first time, and I had a side effect I've never heard of or experienced from other opiates. It leaves an odd discomfort (I guess in the muscles) around my right shoulder. It's a hard feeling to describe.. It doesn't hurt, it's just annoyingly uncomfortable. I've taken it 3 times total so far in the span of about 2 weeks, and it's always my right shoulder. That just seems sooo random. If anyone has an explanation for it I'd be curious to knw what it is.
I guess I should note that I am not taking it for pain, but it is definitely not an overdose effect(only 15mg each time). By the way you can hold back your anti-drug speeches. Believe it or not, some people(ala me) do have the will power to take opiates and never go overboard.
