I found a half pill. It's dark yellow, thick capsule shape and is mostly brown on the inside. Since I only have a half, it's impossible to tell what the imprint is. It looks like it could be a V or K if sideways on the pill. I found one other question similar to this one, but no real answer. Someone suggested it could be Sam-E, a supplement of some kind? But I cannot find any images for this drug either.
