I sent a PM to you, suggesting you post your own thread about your upcoming surgery. There is a lot of good advice and support on the forum. Several people have had a thyroidectomy in the recent past. Kimberly's suggestion is very helpful too, to use the search engine.
You'll read a lot about what to expect both before and after the surgery. So glad you are moving forward on this, so you can begin to get your life back. It is a long process, but it will work.
Your teenagers might appreciate reading about Graves' too. There are good references to explain what it is like, not only for the person who has it, but for the family members.
