Also have you looked into Mast Cell Activation Syndrome. Best way for me to describe what can happen is - not allergic to a lot but react to everything. Treating that has been one of my best helps.I considered that Issie...
But no it certainly wasn't detox. I started having the worst stomach pains ever after eating anything and than it just went straight downhill... I had basically only pain before that (alos insomnia, mild GI problems), and after I got a whole new list of symptoms: brainfog, much much much more pain, weakness, fatigue, photo sensitivity, not to mension the depression like going through hell. It didn't got better... I kept being vegan but it just got worse... I'm now for a while getting slowly better but I begun eating meat and eggs again, stopped going to the university and stopped working for total fully pacing, started taking lyrica (before, with the allodynina I simply couldn't be in the world, everything that touched me hurt so bad... I felt like I needed to be on a white endless space floating.), but I'm still a loot worse than I was before trying to go vegan. :\
I think somehow I developed a fruit malabsorption, cause now I can't get close to fruits. It messed something in my gut that triggered it all... Before I use to have GI problems and all but nothing I ate was such a big problem (I used to do the most crazy experiences in the kitchen hehe) and I used to drink a lot... it's pretty strange.
There was also the fact that I stopped taking Cymbalta at the same time (I was only taking 30mg, for 3-4 months and it was of no help at all), so I wondered if it could be some kind permanent/delayed damage of the Cymbalta or the Cymbalta withdrawl, but all doctors assure me that this was impossible. (I mean, I had a lot of withdrawl sympyoms but they went away before going downhill...)
