We're all so different in our likes and dislikes, etc.
Anyway, just for the record: I completely cut out all sodas when I did IP and have not added them back in after 8 months of maintenance. I just feel better without them.
Never used WF either.
As for sugar free gum: When I was on IP I would have a HALF piece of gum some days. If I needed more, I'd have the other half. It's a tiny piece and I don't think it hindered my weight loss. Now on maintenance I still have a half piece at a time.
