Sounds great. Diet is key but diet alone will probably not cure yourself. Continue to eat well for LIFE. I learned my lesson!!! Have you looked into liver flushing. I am speaking from experience that I did much better when I started liver flushing. I also folllow the plant based Alkaline diet and body type diet from Andreas Moritz . You should not be frustrated at all since this is good news. Since you have had this for over 10 years it's going to take time like 6 months or so. So just pace yourself relax and enjoy the experience. When it gets tough slow down. I'm now symptom free without drugs so it's totally worth it. If you read the recommended messages in each forum you will see the success stories out there.
I would also try the Salt Water Flush.
Sauna at the gym? to release toxins
digestive enzymes? give your liver and body a break
Gluten free grains with bread or even cereal
Ther's always more that you can do! So add something new every week
