I've been lurking on this board for a while and sincerely hope for advice from people who've been there. Please, help, as I'm about ready to throw in the towel.
I got my linguals 3 weeks ago (both top and bottom) and speaking is very difficult. The fundamental problem is that the braces make the space so narrow between my first molars, that my tongue is just not able to stretch and bend into the shape it needs to produce those right sounds ('ch', 'g', 'str' and 'sh' sounds are the worst).
All the studies that I have read on lingual braces indicate that patients experience 'some' or 'minor' speech problems, such as a lisp, that was temporary and resolved itself within 2 weeks. This is not my experience at all; I wish the lisp was it! I actually had my GP write me a referral to a speech language pathologist, that's how bad it is.
The main reason I got linguals was that the vanity got the best of me and I wanted them to be hidden. I had to tell everyone that I was wearing them as everybody keeps asking me 'Why are you talking funny?' or 'What's wrong with your mouth?', or, my favourite, 'I didn't understand what you said.' (I practically want to cry after that one.)

I'm at a loss since I've been practicing outloud every day. I actually have a list 3 pages long of problematic words that I go over dilligently everyday. Can anyone, please, tell me what else I could do? I talk slowly since if I talked any faster, it would be incomprehensible. I drink water. I gargle with salt 5x a day to help my tongue heal.
Honestly, I cannot believe I'm actually saying this given the cost and pain and suffering to date, but if this does not improve soon, I'm seriously considering having them taken out. Unless I can produce more space between my first molars, I just don't see this for the next 2 years without the ability to talk properly. Please, help! Anyone experience anything like this?
I should add that before this I was told I had a linguistic talent as I'm fluently tri-langual and can speak 2 other languages in addition to that. Or, I should say, I was fluent, rather, as now I am just as stumped in all!
