There is a lot of gratitude, empathy and sympathy for the troops particularly when you consider people's disregard or even belligerence towards troops after the Korean and Viet Nam eras. Things have changed for the better and one of the driving forces in the anti-war camps is getting the troops home. In many ways this sentiment is counter productive to winning a war. Whatever the case, whatever the sentiment towards the Iraq campaign, people understand and appreciate the role of the soldier more so now than in the past IMO.
You ARE appreciated and missed. You can tell that to everyone deployed with you.
I'd say for the money, PowerFull and GABA are the best sleep combo. ZMA would be beneficial too since your probably sweating out all of your Mg. Nimbus' Posiedon would be a great daily addition to help cope with the coming heat and stress.
Stay safe bro, and remember you can always bug AM for advice at anytime.
