As others have said, it's fine to combine them, although some people may not find it as pleasant. Opioids definitely come into their own when you're crashing from a stim, although the combination can be fun too - it's personal preference..
There is a myth that taking uppers and downers together are dangerous. This isn't the case - there is no intrinsic danger at all, and it doesn't "confuse your heart" or anything like that. The danger comes from one masking the other, leading to someone taking a dangerously high level of downers without realising, then overdosing when the stim wears off - so be careful with your dosages and don't take more hydromorphone than you usually would, or mix it with other CNS depressants such as alcohol or benzos.
