Hi and welcome back!
It's fine if you fall off the boat, just climb back on and go forward like nothing happened. Others warned against IFing early on. Not me! It's a great way to get out from under the tyranny of "three (arbitrary) meals a day." Reading through your journal reminded me of me starting out.
Alcohol. I have been always a big drinker. But have all but given it up while trying to lose weight. I've done this for a couple of reasons. The main one is that it stalls my weight loss. When you drink, your body has to deal with the alcohol right away, because it's poison, so your liver gets busy processing it and all other functions take a back seat. Toss in a big meal at this time and it gets stored as fat, because you're burning alcohol.
The other reason is since alcohol impairs your judgement (have you met my ex-wife?) while drinking, it is harder to adhere to Primal eating. While you might enter the restaurant with noble intentions, a few drinks and you leave after eating two sides, extra bread and dessert.
I love beer. But I've stopped drinking it. I'm confident that there will still be some beer left for me when I am a more reasonable weight.
Best of luck to you!
