Sonic - I am just like you. No problem ever for me with alcohol; I could take it or leave it. I did leave it years ago though b/c of my spouse's problems with it. Opiates, however, sucked me in big time. The first one I took about 30 yrs ago gave me a feeling I never had before. Did not become an addict at first, but really liked the feeling. However, have been on the addict roller coaster for about 20 yrs. Clean for almost 7 months now. About the longest time I have ever gone and I think I am finally on the right road at almost 58 yrs old.
We appear to all be wired differently. Let's face it. There are many people who take or leave opiates. Some people cannot stand the affects that we all crave.
Keep up the good fight and keep posting.
