Hypersensitivity - to drugs e.g. caffeine also?

Post Reply New Topic

Many people feel a core feature of Asperger/AS is hypersensitivity of the senses e.g. to sound (see for example http://www.wrongplanet.net/postp2153077.html#2153077).

I also seem to be very sensitive to caffeine, chocolate, alcohol - i.e. a small dose can have a big effect - is this common?

Thanks

I react differently to some substances. When I use caffeine I can get more sleepy or it has little effect.
Also some combinations can give strange reactions.

So it does not seem like hypersensitivity in my case, but some alternate chemistry.

Yes, this is true for me. Small amounts of both caffeine and alcohol make me feel very dizzy and unwell. Also junk food and food with artificial additives in it tend to make me feel physically overwhelmed - in the same way I feel from too much sensory stimulation. I need to eat very simple, natural food to feel at my best.

I react differently on some drugs - some have a stronger effect, some a lesser effect, some a different effect.

I am famous for appearing still sober, even highly intoxicated with alcohol. I do realize that my brain does not work properly any more whilst others do think that I am still sober.

This is true for me, as well. I can get high off of literally one drop of alcohol, and a single cup of coffee can make me very nervous. Once I drank a cup of coffee before a test and made a bunch of stupid mistakes on it because of how nervous I got. Chocolate, on the other hand, helps me study somehow.

Nope no caffeine problem. Just hypersensitivity to light and certain high sound frequencies.

coffee makes me super gassy and wakes me want to fall asleep on the spot, liquor makes me dizzy and hot in my entire body, weed makes me go to Jupiter and back.

My alcohol tolerance is pretty normal, as is my reaction to various other drugs (otc, prescription, and illicit), although i tend to need higher doses of some of them to have the desired effect. However, I am highly sensitive to stimulants of any sort. Caffiene, dextroamphetamine, methylphenidate, theophylline, whatever. I cannot drink coffee because of the caffiene content, and I have to limit my tea drinking. Energy drinks make me physically ill.

SAME HERE! Milk can keep me awake, Caffiene makes me sleepier, if anything, and pain killers JUST DON'T WORK! BTW I am a chocoholic, and alcohol is fine.

Painkillers work with me - but it depends: Paracetamol and acetylsalicylic acid (Aspirin) work quite normal, when it come to codeine or other opiates likes (Tramadol) I need quite high amounts to have any effect.

Caffeine: I don't think I here anyway typical, but this has more to do that I grow up in a family of strong coffee drinker, so I am used to ten cups of coffee a day since the age of 14 or so. I just need this stuff to function in any respect.

Definitely. Especially alcohol, caffeine and processed foods like sugar and flour. I feel drugged on that stuff. And as far as meds go if there is a side effect to be felt, I feel it!

yeah i couldnt drink caffeine drinks when i was little cuz i would faint especially in the summer time.
the only caffeine drink i like is mountain dew and i dont drink it as much.

Coffee just wakes me up and actually makes me get more organised. It overheats me though so I can never finish it. I'm drunk off 2-3 glasses of alcohol.
But I'm with you on food. I get ill from deep fried and processed food. I only can eat a little junk. I'm only at my best when I have healthy food too, apart from wheat and dairy. Dairy food/drinks is like having a sleeping potion and wheat gives me indigestion. Soft drinks give me stomach cramps and the bubbles hurt my tongue. I'm so very sensitive to food, even the mildest chili is hot to me. And I'm allergic to oranges.
The strange thing is I need a higher dosage of a painkiller for them to work. You'd think I'd be knocked out after one.

Like a few others here, caffeine seems to have little effect on the men in my family, including myself. while it doesn't make me sleepy, and prevents me from falling asleep, I don't get riled up by it in any way, and find myself drinking soda and coffee for flavor more so than caffeine rushes.

Absolutely. I had half a small latte at 11am, and couldn't sleep that night. But when I get novocaine at the dentist, it doesn't take effect right away and I end up feeling the whole thing, then my mouth is numb hours afterward.

Coffe works the way it should with me...at first. I get a pretty intense headache if I stop...about 48 hours later. Sugar has always been a problem...I've tested negative for diabetes many times. Chocolate is my weakness...the hell with the way I feel.

But eating a gingerbread man makes me feel like...

a cannibal.
