No ARM CPU, but there was an aftermarket conversion called the X62[0], with upgraded display and Intel Broadwell CPU. I think it's mostly been supplanted by an X201 conversion, the X210[1].
Part of amphetamine's effects include an increase in energy during the day, which helps make you tired in the evening when it wears off.
Sometimes instant release (Adderrall or Dexedrine) is prescribed to supplement a time release version, particularly if you experience "the 5 o'clock crash".
If your on something like Vyvanse, you might have to up the dose after months, possibly even years, as your tolerance builds. Supposedly it's possible to reach a dose that balances against your metabolism, and you won't need to increase it again.
I found that, at a high enough dose, my jaw started clenching quite a bit, and I had the occasional heart murmurs. I do drink the equivalent of 3-4 cups of coffee on a regular basis.
If anyone experiences those side effects, I highly recommend chelated magnesium. Worked wonders for me.
It's common where I am to get spam phone calls that spoof Caller ID to match the area code and first 3 digits of your own number, to appear "local" and make you think it might be someone you know.
I tend to get calls in bursts. Sometimes it's the same robocall 3 times a day for a week.
Phone companies also reuse numbers, and their lists of active numbers leak now and then, so even if you get a "new" number, you can still get spam. I don't know how feasible it is for spammers to wardial every number, but it might be possible.
And I think there used to be a bug where certain characters in a text could crash am iPhone, or something to that effect.
Apple has spam detection in the Messages app now. If it's anything like email, spammers will try anything to bypass it, like replacing characters.
So in conclusion, there's not much you can do about it until phone companies fix Caller ID.
