Thank you ladies. I figure that if I did this much research. I might as well make a choice and pick one, I know what you are saying though. I have read a lot. like, a lot. It's hard to tell what the effects are for one person vs another because it doesn't mention what they are also taking and/or other substances etc. so, it's still up in the air. I would greatly appreciate any opinions you might have of the four I mentioned though. Thanks for your replies.
