UPDATE:
Just wanted to update anyone who was waiting to hear how I am doing with the light therapy. I've been using it for a week and I am seeing a noticeable difference.
Before I started using it, I was exhausted all day, irritable, and felt sad for no reason. After a week of using the light for 30 minutes each morning, I seem to have more energy and the irritability and sadness only show up in little spurts here and there instead of constantly.
be warned..this doesnt remove your symptoms entirely. I had one day (the day I started my period, lol) when I was weepy and grouchy but in previous times, I have had a complete meltdown on period day. I didnt even cry this time.
Overall, I feel better and have been down on the floor playing with my toddler, getting more housework done and am able to pay more attention to my preteens and husband. I would recommend a SAD light to anyone who needs a boost.
Now...the only drawbacks, imo...you have to sit a foot away from the light. Thats not a big deal in of itself but because you sit that close, I find it to be hard on the eyes. This light is super-bright...brighter than I was expecting. The first day, I got a headache that lasted for a few hours until I finally took something for it (duh!) After that, it didnt bother me again. I also felt slightly nauseous a few times but it's probably because I drink coffee and dont have breakfast with it. The nausea for me went goes away within a half hour of shutting it off and grabbing a bite to eat. It could be that I need to cut back my time to 20 minutes, but I enjoy the results so much as it is that I dont want to cut back.
anyhow..thats how its working for me. Its not a miracle worker but I definitely see an improvement so I think it is well worth the money.
Also, I bought this with a lot of skepticism and assumed that it wouldnt work for me but I do understand now why people buy them because they do work.
