When I first read this, I had to make sure it wasn't my own post from a while back...
First off, it's ok. Your human. I was the same as you (except the cigarettes). You'll find that having Christ's presence in your life (and after converting, having his physical presence in your body!) really changes you. While I could still stand to loose a few pounds, I no longer struggle as strongly with my old sins.
This is something I had to tell myself when I was in one of these little slums a new convert goes through : "Get off of your butt and go to Church!" (pretend I said the "a-word", to make it more effective
Seriously, it's simply laziness. If any convert or hopeful convert tells you they haven't experienced this, their not Orthodox. There is a reason that we hear so often in the services of the Church supplications to God not to be silent to us, to hear us
. The reason these are in there is because, even the composers of the liturgical services sometimes didn't feel God's presence! They, whom we so often pray to/for, had their struggles, too. That's why they put it in the liturgy, because everyone struggles.
This is a quote that I've read that I think applies in your situation, as well as my own. It is by a man whom I hope to meet some time before I die.
"Holiness comes only to those who struggle.
Not an hour should pass without taking time to examine our heart, for the hour of judgement can come at any time, and we must be ready to give account to God for our life.
There is no spiritual improvement if we do not seek to please God with holiness of life. If we find good in our deeds, we must attribute it to God. If we find we've neglected our spiritual struggle, and acted with foolish abandon, we, in our weakness, must turn to God in repentance.
We must resolve to turn ourselves around, with God's help, and fight against the enemy of our souls. Holiness comes only to those who struggle."

You see? We will struggle. The question is, will we turn to God?
I'm not knowleadgeable like I was when I was first converting. I need to brush up on my reading. I'm no saint, either. I do remember that very, very commonly said saying among Orthodox that has been etched into my head, of which I'm reminded daily (whether I like it or not!)
"When you fall, get back up!"
It's as simple as this. Go to Church!!! Get to your prayer corner, ask for forgiveness from God (never stop doing this!), and go be with Orthodox faithful who will help you boost your faith!!! Dry spells like this often make one question his faith in God and his Church, but you will come out stronger for it in the end! I can say this, because I'm still recovering from a "dry spell", myself.
Second in importance only to prayer, is to go be with Orthodox faithful. We here on OC.net are nice to talk too, but you need to be with real people, in a real Church. Hold the hands of the old ladies, sneeze at the incense, and get prosphoro crumbs allover the place! Just go to Church, you'll feel so much better!!!
Now, let me try taking my own advice...
Your in my prayers!
