MB, glad to know you are taking it easy and taking the time to order your thoughts. That is the 3rd step. Way to go!
Feel free to e-mail me or PM me anytime. If you need someone to talk to, PM me and I'll give you my IM handle.
Regarding meds, yes the meds help the serotonin concentration to go up faster than with exercising, however they should be the last resort. With the exception of homeophatics, all meds are in some degree toxic. No, of course I am not saying you will get intoxicated and die because a little Ritalin (used for ADD) or Paxil. I am only telling you that they should be taken with discretion. Mainly for the points Mr. Drisley already pointed out. And, even when they don't create physical dependance they create psychological dependance in some cases.
@ Tim and Juppy: LMAO

. But no, it's not because of blood why I am not practicioning as a doc. In college I was the first to jump onto the patients to do the surgeries. With my methodical ways and my dexterity I could be one of the best surgeons, I know dat. It's just that computers got the hold of me and fascinated me even more than medicine. But you should see me working, I apply the medical methods I learnt in college to repair PCs, and those methods sure have helped me a lot in this trade!
