Caffeine, definitely! Usually always makes me more spacy, "out of it" can increase my DP/DR.
There was at least one clinical study on this. A double blind study where a woman w/DP was given tablets I believe... some w/caffeine, some w/out (sugar pills or something). The test revealed that her levels of DP increased on the caffeine, significantly.
Makes perfect sense to me as others have stated here.
I don't know where that study is now and it was very limited, but there's an abstract somewhere at Pubmed... I'm certain.
Yup, a stimulant, that doesn't help an already overstimulate person as I'd say we all are here (or a majority). As John mentioned though, it depends on the individual.
But if you notice an increase of symptoms after a cuppa, or some caffeinated soda (I don't drink that often), it's more than likely the caffeine. Yes, my one vice that I HATE to get rid of.
I have "half-calf" in the morning. Never after 12pm too. Then my sleep is a disaster.
Best,
DAMN I LOVE COFFEE! THE TASTE! THE AROMA! IT'S ADDICTING. :shock:
