Yes, I had a refeed yesterday actually, about 7-8 days in. Did feel that I needed it. Felt somewhat lethargic afterwards though, even though I only had just over 300g carbs (36g of which was fibre), which I used to do regularly. Is that normal? I wasn't quite sure how high to go. I'll see how I feel the next week or so anyway, but so far I'm liking it, and my training is going well. Would you suggest I up calories a bit on workout days, still high fat though? I'm currently about 2500 on rest AND training days, and did about 2800 on my refeed (dropped fat to just under 50g, where it's been around 150g every other day). Definitely feel more hungry on my training days though. I have been taking the Karbolyn (50g) intra... can't say what effect that's had though, too early to say most likely.
