Hi I am thinking of trying the antihistamine combination suggested to see if this helps my POTS, however these meds are anticholinergic and thus oppose the functions of the Vagus nerve which is something I don’t want. I already have sympathetic over activation plus dry eyes dry mouth and sluggish digestion. I also recently ordered some Parasym Plus which costs too much to potentially negate its effects by taking antihistamines.
I would love to hear others’ thoughts or experiences on this issue. I live in the UK so access to appropriate testing or doctors knowledgeable in these conditions is very limited.
