is increase serotonin. You can also increase serotonin with tryptophan supplements and B6. It is increasing serotonin that improves PAIN.

Wellbutrin affects dopamine. (not great for pain)

I hit rock bottom last year. Even after changing my shifts to eliminate nights, I was not great. I didn't decide to do the visor until Feb...making decisions is not so easy when depressed, you know.

This is the one I bought:

It now lives at my son's house....because he needed it too. Only he uses his at 4pm and I use mine in the morning. He has has mild anxiety all his ADD life, and likes the visor also for the winter. ( I gave him mine for Xmas). I've never increased the power and only use it for 1/2 hr. Overuse of light can throw you into hypomania if you are so inclined, so I remain very conservative. Can't spook my husband you know at this late date (40yrs marriage)...!

So I now have a new one! LOL

If it is going to work, you should see effects within a week. The thing has a 30 day money back guarantee. I'd suggest B6 with it, and tryptophan perhaps, since these are precursors to serotonin synthesis. You take the tryptophan at night with a little sweet thing (about 100cal) away from protein, and it will zip right thru the blood brain barrier and start working for you.
When I was low, my neck was killing me, and my back, and boink...light fixed it. My arthritis pain is soooo much better with no pain pills. I do an Aleve liquigel when the weather attacks me, but that is like once a week now.

You know that antidepressants cause downregulation of other neurotransmitters in the brain...it is the brain's way of compensating. So using Wellbutrin increases dopamine and DECREASES SEROTONIN.
SSRIs increase serotonin in the synapse (do not increase production) but downregulate dopamine. So I don't think the Wellbutrin is serving people with pain issues well. JMO
