Welcome, Jean,
Your first post is good and we are happy to help. Have you been reading through all the different forums? The Newbie Question forum has two ”stickies", posts fixed at the top, with many tips to help you through the first days of transitioning to being a fat-burner. It is helpful that you have been eating somewhat low carb already and may breeze through. The Atkins forum has the Induction food rules at the top of it from the 2002 edition, note there are some limits on dairy products if you plan to follow that. The recipe forums have induction recipes indexed. So Much good information here to help you succeed improving your health.
Have you seen a doctor about the swelling to determine if it is common edema or another cause. Could it be related to a medication that might have an alternative? I don't want an answer, just know that there are many causes for swelling and assume you have had checked them by now.
All the Best,
