In reply to How long before seeing results from lightbox?, posted by KaraS on March 8, 2005, at 15:09:00
> I started using one regularly about 2 weeks ago. I've used it most days for at least an hour a day. (I'm also taking 2,000 IU of vitamin D.)
From the Cleveland Clinic on light therapy (10,000 lux):
"Most people notice improvement in 2 to 4 days. In some cases, symptoms may not improve for several weeks. If symptoms are worsening or do not improve after 4 to 6 weeks of therapy, see your physician. You may require a change in treatment."
