I actually just bought a day lamp for the winter. I tested it out for 10 minutes and I felt a natural lift in my mood but I’m not sure it helped with negatives.
I know that people with mood components to their disorder shouldn’t use it because it can trigger mania. I remember a friend with bipolar telling me her to doctor told her that.
Anyhow, does anybody else care to chime in about their experience with light therapy?
