It's the only thing that got me through the first three months, seriously! I think it was about all I had in my tummy many days, a mug for breakfast (I was shattered anyway so who knew the difference) and a mug before bed. DH would make dinner and Id stare at it and push it away and make an Ovaltine! At least 2 mugs kept a few hundred calories in me and loads of calcium and vitamins! I feel like the UK version had 100% of the required folate but the jar I have here is only 45% - could be that it is more fortified in the UK or maybe I am remembering wrong, not sure, but I know it is a good source especially if you are struggling to keep food in!
