Information on DCA and methadone

Hello all,
I'm looking for information on DCA. My dad was diagnosed with an inoperable glioblastoma in December 2015. He's doing pretty well at the moment and we're happy with his treatment. But we want to be prepared for the worst case and that's why I'm interested in DCA.
We live in Germany and as many other cancer patients my dad is taking methadone as part of his cocktail. That's also my main concern because I couldn't find any information on whether methadone and DCA can be combined (I read that you need to be careful with cannabinoids which could be problematic as methadone uses the same receptors). My dad's tumor was stable for a year and then started shrinking in December 2016. As you can imagine we're extremely happy and don't want to omit any of the drugs he's taking at the moment:
- Temodar (still on 5/23)
- methadone
- Optune TTF
- dexamethasone  (tapering 0,5 mg)
- Omega 3
- Vitamin D
- Levetiracetam
- Coriolus versicolor (PSK)
- broccoli sprouts
- Eliqius (blood-thinner)
If you have any information on the combination of DCA with our cocktail, please let me know. I'd also like to know whether you really have to be careful with the dosage in brain tumor patients. I read some really scary stories online, they said that the combination of DCA and caffeine was dangerous.
Thanks a lot!!

Should we drink that coffee or not- the dilemma.

I am wondering what was the whole worrying about caffeine and dca combination  and if it was not  to cause tumor lysis or for some other reason. Here is a link to a study showing that coffeine has some positive effect for glioblastoma. I am not advising anybody to drink just wondering myself what to advise my brother.

Ahmad did not have any side effects..except recently when we introduced Prozac..I have the feeling this medication is making restless..and very nervous..I am not sure..
I need feedback from those taking Prozac (fluoxetine)..is this dose 20mg enough? And will the side effects reduce with time? I am also worried when using with verapamil..should I reduce the verapamil to 280 mg??

We will start Accutane after next round of CCNU..
God bless u all..and help us in our battle.
