I would maybe take things one step at a time. For instance, week one quit coffee, week two quit smoking, and week three quit the bad foods, etc. You need to pace yourself because this is a marathon and not a sprint.
Plan on a 6-18 month recovery time to get over candida overgrowth. Doing things too much or quickly can make you feel bad and its best not to stress the body by doin too much at once.
The tongue will still colored in 6 months, but not as bad. Its not going to go away overnight.
One thing I would consider trying is oil pulling which will pull out the candida from your mouth.
I’d consider trying out an herb called ashwagandha which can help with anxiety, depression, etc.
We developed a general plan to get better if you are interested:
Molybdenum can be used to help prevent die-off. There’s a lot of stuff you can take for sleep as well (mentioned on the forum).
