I would say that after being off for 10 days it might be a good idea to do Induction for 3-4 days to get back into ketosis and get you back on track, kick re-addictions, etc. Then, you could go back to however you were LCing before you went off track.
Please, don't beat yourself up and get yourself all depressed and stressed. It doesn't help and it could make things worse for you. I've been there, done that and it doesn't do anybody any good.
The best thing to do is to just make the next thing you eat LC. Then the next and the next. Don't make a big production of it, just do it and consciously choose LC foods only. Then, if you do get tempted to have something that's not LC, remind yourself that you're now back on track (even if it's just 1-2 meals back into it) and you don't want to start all over AGAIN!
Journal (either here or on paper) and write down exactly how you feel right now after cheating for those days. Go back and read it if you're tempted to cheat again and remind yourself why it's such a bad idea and how you'll feel about it afterwards. Another thing is to remind yourself that it takes 2-3 days to get back into ketosis so a cheat is going to set you back those 2-3 days, not to mention the 'carb flu', cravings, withdrawals, water-weight gained, feeling like crud physically and emotionally. It's just not worth it!!!
Don't forget that most likely 1-3 lbs of that 5 you gained are probably water.
Oh, one last thing
I went off and on, off and on, and each time I gained and lost the same 5-6 pounds. Guess what? Each time it got a little harder to lose that weight and then finally, even with sticking strictly to plan I couldn't get it to come off!! I finally have now but it was such a struggle, so depressing and frustrating. Don't do that to yourself! It was terrible and I almost gave up completely.
