Hi there and WELCOME. I thought I was a big fan of fiber, but you must REALLY be a big fan to go on and actually use it in your user name. It is great stuff, isn't it?
Flail around here all you like. This is a sensational place to get back on track. Lots of encouragement, support and advice.
I urge you to come check out the 100 lb club. located in the Support Groups section. There are many ongoing threads there which I am sure you will find beneficial. With loads of people who are in your same exact shoes.
Good luck to you on your journey. I look forward to hearing lots more from you.
