Caffeine. I LOVE IT!
This is something which I realized about a month or so ago.
I had the same problem as you. I worked out 3-4 times a week, ate healthy, got 8 hours of sleep a night, drank lots of water, ate fruit, etc...
It didn't help.
Recently at work, I started to buy these 25 cent Cafe Mocha's from the machine. They are GOOD.
The caffeine changed me. It made me more talkative. It made me more confident. I was C+F... mentally alert... was having fun, and being one of those outgoing, talkative fun guys that everyone loves.
Like it said, it changed me. People would start to see me differently. People started to like me. I made friends. I was happy.
HOWEVER, about two hours later... the result? You get tired and depressed.
What did I do? I had another one. 25 cents, that's nothing.
I'd end up drinking 3 Cafe Mocha's a day. The only other side effect that I know of... is that it may disrupt your sleep. Caffeine is also an addictive drug... you'll have to have it every morning if it messes with your sleeping.
My whole goal is to use caffeine as a crutch. It's an experiment, if you will. Maybe if I do this everyday... and continue to act this way... it will help my confidence, make me more comfortable with those people and meeting people... and eventually wear off on me. I might become this person... and it might HELP me.
Any thoughts?
