Thanks girls, you've given me a lot of food for thought. I know it's something I'll have to discuss with my ob when the time comes, and as I have no thyroid, I will have to see an endocrinologist throughout pregnancy too, so I'm sure between all the drs, we'll come up with something we're all comfortable with. I'm thinking I would prefer to ween over 12 weeks, rather than cold turkey. But hey, I'm not counting my chickens just yet ;-) Thanks again for your input x
