Okay, this is a weird one. I've noticed if you fill your thirst meter completely, no matter how you do it, it resets the counter. Even if you drink plasma packs, plasma janes, and/or eat plasma fruit, it will reset.
The solution is to just not fill it. Stick with keeping your thirst bar at no more than 3/4 full but make sure it doesn't go into the red.
Quoting myself because this is the problem (I know the OP has seen it already). Hopefully it will be fixed by EA soon. Once I quit filling my thirst meter, I was able to complete the aspiration. It's annoying and it shouldn't be this way, but drinking anything until the thirst bar is full causes the reset.
Edit: At least, that's how it worked for me. Though just keeping track yourself and finishing the milestone via cheat is also a good solution until/if it's fixed.
