I have been drinking DDW (yes its f*****g expensive) for just under 2 months. I have improved in this time HOWEVER I've been doing other things (like I always do) so cannot attribute it to DD. I apologies as this is annoying for people reading this thread. On the kruse forums member Jan has had significant health improvements for his conditions about 3 weeks in. Not many others have been trying it though. Drinking it one of won't do much. If he drinks a bottle for a month straight, then I'd like to see the results. The problem with too much D is with slowing down reactions, making certain bonds more stable/unstable, and different interactions with light. To see these effects translated to symptoms would take some time I would think.
