Hi Carly
Sorry you fainted, must feel quite scary.
You haven't got your stats on your user CP so I can't tell how long you've been doing LL, what stage you are at or how much you've lost etc.
All these things make a difference. Have you been on packs since September?
Are you drinking plenty of water, little and often? Not exercising too much?
You could ring NHS Direct or your GP Surgery tomorrow if you are concerned.
Or it could be nothing related to LL at all................?
