Welcome Sheena, and congratulations on taking control. Sorry, I have no experience of thyroid issues, so no help on that front. 🙁
I only started BSD and joined this forum last Monday, but already I have been overwhelmed by how welcoming and supportive everyone is, so I am sure you will find the same. Really pleased to have you aboard.
I am amazed and very happy that I have managed to lose 8lbs in 7 days – but I have been REALLY (probably over) strict with myself as I know from experience that if the scales don’t drop quite quickly at the beginning, I will give up! I do know however that I cannot possibly continue losing at this rate, but now I am determined to lose the 28lbs goal I set myself (and hopefully more) and am prepared for a much slower rate of loss.
Be prepared for a bout of carb flu – not everyone gets it, but I did, and not very pleasant. Just fight your way through if it happens to you, it generally only lasts a few days and it is a sign that your body is learning to switch from burning carbs to burning fat, so if it hits you, look upon it as a GOOD thing, and stick with it.
Tell everyone what you are doing so they can support you and be kind to yourself. Good luck and looking forward to hearing your first week’s results.
