SAD lights won't affect your vitamin D levels ... they emit the wrong type of the UV light spectrum to generate vitamin D. However, I have tried both. Vitamin D3 supplements definitely helps me reduce inflammation. And the SAD lights do perk me up. I don't get depression related to SAD. But I do suffer from fatigue and idiopathic hypersomnia, which the SAD lights do help. The lights perk me up and I don't get tired until much later in the day.
I had a very, very bad reaction to Advil Liqui-Gels about a month-and-a-half ago (been gluten free since May). When I took it, the only thing on my mind was my pain and that I couldn't take Tylenol because of the corn. I totally forgot Advil Liqui-Gels were wheat derived. On top of having to avoid gluten, I also must avoid corn and soy, among many other problem foods. Within 1/2 hour of taking the Advil Liqui-Gels, besides getting nausea and sharp stomach pains, I started getting all sorts of neurological problems: twitching eye, numbness, tingling, burning and stinging scalp, dizziness and vertigo, weakness ... all so bad I thought I was going to have to go to the hospital. Only good thing about it was it did take care of the pain I took it for in the first place.
Advil used to be my painkiller of choice, and I hadn't noticed any problems before going gluten free. But now that I am gluten free, I definitely notice it being a problem. I have had some of those neurological problems before going gluten free, but never was able to associate it with anything, probably because gluten and Advil were regularly used and my body had been compensating.
Here in the US, most of the liquid form of Advil (think children's elixirs) and the Liqui-Gels are wheat derived. The other forms of Advil are safe for celiacs, IF gluten is the only thing you are having to avoid. If you have to avoid corn, you are out of luck because it is in the non-liquid versions.
I'm sure it can't be much gluten in the Advil Liqui-Gels, but as little as it is, it just isn't safe for me.
Anyone have any suggestions for non wheat, corn or soy based pain killers? Everything I can find has one of those in them. I hear even all prescription pain killers in the US use corn as binders and fillers.
