Anyone else cannot tolerate caffine

I've not been able to tolerate caffine for about 15 years, gradually. I am caffine free now because I cannot tolerate even 1 caffeinated coffee.

I am just wondering if it is linked to anything possibly or if anyone else has this.

It gives me a horrible racing heart, the shakes and I will be wired for hours and wouldnt be able to sleep. Sometimes it gives me an upset stomach.

Just wondering if anyone else is the same and if its linked to something else.

Me too. I used to love a coffee or two. But gradually, I had to only drink them in the morning, because anything after lunchtime would keep me awake. And now, I can't have coffee at all. Even an 8am coffee will mean a sleepless night. Also gives me an increased heart rate, and more than one coffee will give me borderline palpitations.

I am bouncy bouncing of the walls and running to the toilet.

My dad can’t. If he has even one drink he’s constantly in the loo and wired to the moon. I think it’s just an individual thing. I’m caffeinated to the eyeballs most of the time and don’t have any bad side effects.

Yes me. It makes brings on hypoglycemia symptoms for me. If I had a coffee with no breakfast I'd be on the floor.
I LOVE some of the coffee substitutes: barley and chicory. Much nicer.

I had a colleague was allergic to caffeine but I can’t remember exactly what effect it had on him, certainly an upset stomach.

I'm the same with decongestants!

I had my first coffee at 17 and I was so unwell afterwards I couldn't get out of bed for three days. I've never had caffeine since and I'm now 41.

I stopped being able to tolerate caffeine a while ago. It started with coffee and I'd have a racing heart, anxiety, feel wired, couldn't sleep etc. I then found that if I missed my single cup of tea in a morning, I had a raging headache so I stopped drinking caffeine entirely as it clearly wasn't doing me any good.

I do drink decaf earl grey and occasionally have a decaf gingerbread latte.

We all tolerate caffeine differently. DH could drink coffee all day and have an espresso at night and just fall asleep! I have 1 coffee in the morning and that's it . If I drink caffeine after midday, I can't sleep at night for hours.

Yes, I avoid it. Can’t drink Coca Cola as it gives me diarrhoea. Coffee and tea make me hideously shaky.

it’s the world’s most misused drug!!

Yes . Since been diagnosed with high blood pressure.

Sally2791 · 07/03/2026 20:01

Yes all of the above, very wary of caffeine now

Hellohihola · 07/03/2026 20:01

I cannot tolerate caffeine either. it leaves me extremely short of breath, so much so I cannot hold a conversation or breath properly for hours. I found a cup of tea worse than coffee. Have been like it for 9 years or so
