I had the same problem, but with both upper and lower. The first thing I did was get a do-it-yourself relining kit (Dr. Leonard catalogue on line), and redo the linings of both dentures. The I switched to a powdered dental adhesive, which worked a whole lot better than the gooey stuff. That was over 6 years ago. Although, like you, I still feel like I have a block of plastic in mouth with them in, I reline them myself every two months, and only wear them when I go out of the house. Some people get used to them right away and never have a problem, others just tolerate them for the duration of having them. My biggest problem at first was gagging, but constant wear finally got my mouth used to them, and that stopped. Also -- the dentist explained to me that some people have more of a bottom "dental bridge" (the raised portion of gum that the lower denture sits on) which allows for more suction under the denture, while a flatter bridge decreases the suction. I just used a lot more denture powder. (I use Fixodent too).
I truly hope that you get used to them. I do know that constant wearing them, and having them relined, whether you do it yourself, or have a dentist do it, goes a long way in getting used to them. Have you considered 2 or 4 implanted teeth to hold them tightly in your gum?
