Constipated for 26 yrs. - HELP!

I have been searching the internet and other places for some help. I came across this forum and it looked like you guys might be able to guide me to better colon health. I have been using laxatives for 26 years. The birth of my first child brought on my problems. I have tried over the years to get off of them but always go back to them. If I don't take them, I don't go! I use Natures Sunshine's Senna & LBSII. I have done juice fasts, enemas, colonics and other stuff, but I always go back to the herb laxatives. Over the past year, I have been having problems with bloating whenever I eat. I have tried enzymes, probiotics, etc., they help some, but still major bloating every few days. Can anyone get me started on the program I need to be on to be able to go "poo" on my own without the use of herbal laxatives? I was looking at a product on the internet that someone recommended called "colonblow" does anyone know anything about it? You can find it at www.colonblow.com I would appreciate anyone's help!

Thanks,
