Did Paul’s Romans 7 struggle happen before or after salvation?

Some teach that Romans 7 is a description of Paul’s struggle as a believer. From there, they conclude that any true and consistent victory over sin on this side of heaven is unlikely. However, context makes it clear that Paul was referring to his attempts at keeping the Law before his conversion. In Romans 7, Paul is describing the normal Law-centered life, but not the normal Christ-centered life.
