thanks for your responses to my previous post.
In germany methadone is a huge topic which is often discussed in media.
Dr. Claudia Friesen, who works in a university hospital was the first who randomly discovered the effects on brain tumors.
On April 21 2018 there was a big convention in Würzburg, called the brain information day she talked about her experiences. She told the audience that she knows 79 persons using methadone between 2013 and 2018. 13 of them died, the others survived till this day:
35 of them more than 2 years
25 of them more than 3 years
4 of them more than 4 years
2 of them more than 5 years
Unfortunately there is no clinical study to back her results. Dr. Friesen is fighting to get methadone tested in a real study but there is no big support in the established brain tumor research.
Lots of german researchers doubt her results and even refuted them in a little study. Dr. Friesen argued that their study was done wrong. For example they used another formula of the methadone. Dr. Friesen used D,L-methadone in combination with Temodal.
The idea of methadone is to increase the effect of Temodal.
I hope she gets her study, till then you can trust her or not.
If you want to take methadone, you should start with 3 drops in the morning and evening and increase to 20 - 35 drops two times a day. For example you can take 2 x 3 drops on day one, 2 x 4 on day two and so on and stop when you can not tolerate more. You should then stay on that level. If you want to stop methadone, you have to reduce the dose slowly.
Side effects are mainly constipation but there are lots more possible, especially if you increase or reduce your dose to fast. You can find them in Wikipedia for example. In my experience you need 1 month to get used to it, so be careful and patient.
