Interesting point, but I don't know if it Wellbutrin's nicotinic antagonism can help explain why Wellbutrin just suddenly stopped working for me after two weeks, though.
The two weeks when Wellbutrin did work for me were incredible. My ME/CFS just seemed vanquished. I did not once read the PR forum during that two week period (even though normally I read and post at PR for at least a couple of hours a day), because I found that when you escape from the ME/CFS condition, the world of ME/CFS no longer seems to hold any interest or relevance for you. You automatically start focusing on other things; that's what I noticed happens.
I would hope that all of us here might one day escape from the ME/CFS condition, where we no longer have any need to read ME/CFS related stuff.
Thanks for bringing that up. I read about the anti-inflammatory effects of Wellbutrin:
this study found that Wellbutrin profoundly lowers levels of IL-1beta, TNF-alpha and IFN-gamma, in a mouse LPS-induced inflammation model.
I think this ability of Wellbutrin to lower IL-1beta and TNF-alpha could provide an explanation of how this drug abolished most of my ME/CFS fatigue and cognitive symptoms: if you look at it from the perspective of Michael VanElzakker's sickness behavior model of ME/CFS, in which he proposes that the inflammatory cytokines IL-1beta, TNF-alpha and IL-6, arising from a vagus nerve infection, are causing sickness behavior and thereby ME/CFS, then Wellbutrin's action of potently lowering IL-1beta and TNF-alpha could explain how this drug put me into near remission from ME/CFS, albeit for just two weeks.
But again, why would Wellbutrin provide near remission in this way, and then suddenly stop working after two weeks? I can't figure it out.
