So, getting the downsides of coffee without the upsides of drinking it?

Earlier quoted context omitted.

Are they pure or adulturated with calcium? Most of the caffeine pills I've spotted are not just caffeine and I think this is the chalkiness you would be experiencing.

They’re pure as far as I know. Would calcium be listed as an ingredient?

Yes should be on the box somewhere, they usually claim to add it to reduce bone loss. Example label: https://dailymed.nlm.nih.gov/dailymed/lookup.cfm?setid=0dbca...

I experience a chalky scent from high dose caffeine pills. I don’t think the taste is unique to the intravenous caffeine.

Same, and on occasion I have had coffee do the same.

That's if I'm reading this correctly and you're describing the smell in your blood?

I've been trying to figure out if other people get this too! Finally I'm able to corroborate this. Never thought of it as chalky, to me it's indescribable in a way that one might attempt to approximate with such a word.

Not related to caffeine pills though, I get it from caffeine itself.

Coffee doesn't cause tooth decay. Sugar causes tooth decay. You can drink Coffee without sugar.

Didn’t realise caffeine was used IV in anesthesia. Apparently it speeds up awakening (which makes sense to me as a non-medic). https://theanesthesiaconsultant.com/2019/06/18/intravenous-c...

But the story in OP is that the patient received caffeine IV at the beginning of the surgery (inducing severe anxiety).

Does anyone know why you would do this?

TLDR; participants with cocaine history were administered caffeine IV. At high doses (300mg) they reported some mild euphoria, and a strange taste and/or smell. Ask HN: aside from caffeine, what is the drug of choice around here?

Music. String ensembles are the best, choir is a close second. Rapid response, mild euphoria, no unpleasant side effects. Repeated exposure can induce fatigue, making it an excellent sleep aid.

Anecdote: someone told me she knew some nurses and they knew a quick way to get over hangovers. Quite illegal, but it involves IV.

Don't come at me: I'm not recommending this, I've never done it, and your nurse friends probably won't do it for you.

Edit: TIL it's not illegal. However, in a hospital I'm pretty sure the nurses aren't supposed to do it for free.
