Hi,
I'm no expert on refeed as I haven't ever done it - and not likely to for another 3 or 4 months - so I am not sure. I do know that you must ensure you are out of ketosis before you drink as alcohol and ketosis are not a good mix!
I'm sure one of those with more experience will be able to help you otherwise I would suggest ringing LT themselves and asking. How good is your pharmacist? Would they know?
Good luck.
