I'm just curious about knowing if someone is using. I don't want to stick my head in the sand or be made a fool of. This person will be sitting talking & then just start falling asleep. Complains about different pain a lot. He went off deep end one weekend. Hallucinating for several days, paranoid. Ended up in hospital but not sure what really was going on. Never is real truthful. Recently I found a pill bottle with a Xanax bar in it & a suboxine strip half of a 8 mg. Can you give more of idea what may be going on.
