I quit consuming caffeine 7 long months ago now. I say long months, but rather it wasn't really that long, just the first few weeks where I struggled a little, and now not so bad at all. To confess I do still now and again have a longing for a caffeine jolt, especially with the pace I keep. It was necessary to stop though and an excellent decision for my physical health, and sleep patterns.
This weekend I let go of another vice while I'm away camping. I hope it's as easy.
