I know a speech pathologist (think speech therapy for kids) who also does accent reduction for adults. It's a lot of the same type of thing: learn to make this sound with a different part of your mouth, then practice until you can do it without thinking, and since adults tend to be less cooerced and more engaged, it can go quite quickly.

Without trying to be mean, your writing could use work too. Practice writing more formally: have instead of got (mostly); capitalize things that need capitals, like English and I; spell check; full sentances with subjects and verbs; a space after sentances.

Without trying to be mean, I find it ironic that you suggest using spell checking, yet spell the word "sentence" as "sentance" (as easy enough mistake for a non-native speaker). Sorry I don't mean to pick on you, I just found this amusing.

Ugh. A poor craftsman blames his tools, but my typing quality has gone way down since my phone stopped doing auto-spellcheck for me. Especially since auto-spell check everywhere else untrained my look twice for tricky words before pressing enter skill. :(

Also, it's apparently an easy enough mistake for a native speaker, too. :) English spelling is hard!
