1. The drug addict died and we think it's because he got a bad fix. We will still need to investigate further.2. The drug addict was shaking badly and needed a fix but he was out, so he went out to get some.3. I need my daily fix of chocolate. Any more Ferrero Rocher?
get a bad fixfix = 毒藥的量bad fix = 毒藥的量有誤，也就是服毒過量也可以用詼諧的方法，例如我愛巧克力愛的上癮。
