I may be a little too far on the "new age" spectrum but I'll throw in my 2 cents...
I use full spectrum light bulbs in my house... they say they aren't strong enough to make a difference (like the light boxes) but I think they help. They are a little more expensive than regular bulbs but they fit in normal lights. I do use massage therapy which is a huge help. I also use aroma therapy stuff. Also when push comes to shove I can be the queen of the barter. Is there anything that you can do or trade with someone for some help? Like, possibly trading the clothes your baby has out grown to someone who has a younger baby or is about to have a baby? Another thing that helps me is having an end date (even if you end up having to change it)... knowing when the baby will be on regular food and you can go back on meds. Dunno... just brainstorming.
