Before you comment... you should know that I am fully aware of the health risks of tanning and sun exposure.  I don't want to be lectured on the hazards of tanning...  What I do know is that it makes me feel better.  I don't know if it's connected to some sort of seasonal mood disorder, but when I beginning tanning... I feel good.  Maybe it's as simple as self esteem and thinking that I look a little better with some color... all I know is that it works... for me anyway.  Today I went for the first time (of this season) and even though I was only in there for 7 minutes, I came out feeling better already.
