Ah, sweetie, I know how you feel. I have S.A.D. - it's so not fun when it gets dark by 4pm.

My light therapy lamp cost $125 ($150?). Eight months after I bought it, my ex-bf walked in to my house with the EXACT lamp....from Goodwill. Cost? $6.99. He uses it as a desk lamp.

Keep your eyes peeled: Goodwill (consignment/thrift stores) can be goldmines.
