My first night in a hammock was uncomfortable. The hammock was too taut (not enough sag) and like you, I am not a back sleeper. Add a case of cold butt syndrome from inadequate bottom insulation and it was a problem.
Besides all the useful comments about underquilts and bottom insulation I won't rehash, I had to learn how to get comfortable in my hammock. I hung in my yard. All the time. Every day I could spare a few minutes. I learned to get comfortable in it. I went from short minutes to longer naps. That level of comfort helped me with my hammock anxiety. As Fronkey says, maybe it's not for everyone, but try to get comfortable in it under optimum conditions before making yourself miserable on the trail.
