What is your standard dose?
And out of curiosity are you American?
For some reason Americans seem to be way more adverse to having generic versions of medications, I don’t know if it’s to do with how the FDA does things, or to do with the amount of medication advertising there, but in the UK no-one typically cares if a medication is generic as long as delivery mechanism and dose are the same.
So I’ll almost certainly get a different brand of sertraline each month, and a different brand of dexamphetamine. The only medication which is brand name that I get is Elvanse, but even then that’s produced by different manufacturers but branded all the same, just under licence from the patent owner.
Tbh the hypothermia sounds like vasoconstriction and/or possibly low blood sugar.
The vasoconstriction can be caused by the higher dose, especially if you consume caffeine.
I had to quit coffee for 8 months due to the horrible vasoconstriction/chills I’d get with it, after those 8 months I eventually started drinking tea, without getting chills anywhere near as much, now when I do it’s an indicator that I need food, especially if my hands have a slight jitter.
In all honestly higher doses of methylphenidate can leave you feeling somewhat depersonalised/disassociated, even changes in dose-timings can cause it, taking more smaller doses can also change the methylphenidate/blood concentration which you may be subconsciously picking up on…
Other things that can throw blood concentrations off: Grapefruit (fruit or juice) Vitamin C Excessive coffee/soft drinks
Unironically they’re basically already doing that by having ads longer than the skip button, as you trade off ignoring the ad for the full duration and paying attention when you’re intended video starts for paying attention waiting for the “Skip Ad” button.
Even just that short 5 seconds is enough for an ad to get embedded in your brain with enough repeated exposure.
