I am glad you popped in to let us know you are still going strong. I remember the very first time I was prescribed percs and wanted more. The doctor said there was no way, but it wasn't long before I learned how to finagle a few for this or that.
I wish back then, at your age, I'd realized what I was really facing was addiction and NOT just the desire to feel good.
But, sigh... ten-plus years of on and off the pills later, I've finally managed to stay off them.
So, yeah... stay away from your friends who "use." Too many times after I'd quit, some "well-meaning" friend would toss me a hydro or a vicodin and there I'd go... I finally cut connections with all of those types of "friends."
Congratulations and keep it up!
