I’m a beginning reader, but I used reversals right off the bat; they just make sense to me. Most often, I find that the reversed card indicates the same thing it would upright, but that it’s energy is being blocked or reduced. I also pay attention to the ratio of them to upright cards; if I get a lot of reversals, I see general frustration, maybe self-sabotage. If one makes sense and the other doesn’t, maybe it means that one of them should be interpreted opposite it’s upright meaning, but that the other indicates the positive side of that card is in force, but being hindered in some way.
