If you use forskolin to lower acetylcholine, when you stop you get much worse than before. there is a snap back. transcriptional inducers and their upregulation of acetylcholinesterase does not last. Your acetylcholine action will be more since receptors will be more sensitive. Forskolin was tried for this many times and it fails for this cause.( IMO should never be used)
5 ht1A decreases acetylcholine. acetylcholine can be used for sympathetic and parasympathetic system. 5 ht1A decreases acetylcholine in certain parts of the brain , this is why 5ht1a decreases memory.

In any case this all has nothing to do with all of this anyway, there are no mistakes made by the body. Glutathione recylcing has to be returned this will increases sugar metabolism , this will increase vitamin C recycling , this will increases noradrenaline , body will use fats . and this will allow acetylcholine to come down on its own.
This is how forskolin works, only forskolin should not be used, instead B vitamins should be used along with vitamin C, and may be some copper and histidine.
the goal in all these imbalances is tostart up sugar metabolism , and use fats at the same time. NADPH is impaired so bile acids are gone. and gone for a long time. Without them there is no lipids. Body has to use protein for energy. this raises and keep cortisol high, fats cant be used since noradrenaline is not allowed, since that will decrease Co2. Once you increase b1 and b vitamins, this will increase glutathione recylcing, and increase vitamin C. and increase noradrenaline. vitamin C with NADPH converts cholestrol into bile acids, within couple of weeks if you eat good fats , you will retain lipids. And now your body will run on sugar and lipids at the same time. This will increase stress response.
Cortisol will come down, ammonia will be down. Acetylcholine will have to go down since it is not needed anymore.
Body is not stuck in parasympathetic , it chose to do it on purpose.
