Bests & Worsts Reviews from Amazon

I got a Happy Light about 6 weeks ago, and it has worked very well for me. I've made the mistake a few times of skipping my morning light session and I can always tell by evening - but the next day, after using the lamp, I'm back to normal. I've been dealing with SAD for years and put off buying a lamp, but they are worth every penny. I noticed another reviewer was skeptical a short time after starting to use the HappyLight. FWIW, it can take a week or so for the light therapy to really take effect. Light therapy is also ineffective for 20% of SAD sufferers, so it may not be a problem with the lamp. But my advice is to give it time - if you're part of the 80% it helps, you'll get there with consistent use.
