Trips away can unbalance your routine . I'm sure you will get a couple of stable weeks in soon and be feeling much better and positive and on track .
After the once in a lifetime experience of going to Prague and filling your soul with a different culture , there will also be time to knuckle down and bring down your credit debt . From your words , your partner ( Jeff ? ) sounds like a very solid , stable man . There will be time to work your way back onto the green side of the financial ledger soon enough .
You have done well with your drinking , your weight , your life . You'll keep doing that , have belief in yourself to keep achieving ..and to also traverse the streets of Prague and understand that map .
