Mini blackouts the day after I do meth.

[zachamphetamine]

So I've noticed that the day after I do meth (using a bubble) that the next day nearly everytime I stand up, I get dizzy, I lose my eyesight, for between 10 seconds and one minute, and my sense of balance is severely affected. I suspect it has something to do with blood pressure? But I have neither high nor low blood pressure. This question is mostly just to satisfy my curiousity, but I also wonder if there's something I should be concerned about.

Thanks in advance,

If it's not something you usually experience, then yes it's probably due to changes in blood plasma volume and pressure, since meth acts as a diuretic. To reduce this effect, you could try drinking lots of fluids and eating food (which contains salts you need).
