It was a skinny line, but I was afraid to do the entire thing. I did a full line a little over 6 hours ago. So I was afraid of doing this entire one even though it wasn’t that big in the first place...
Meth has a long half life, so I would say no less than 8 hours as a ballpark figure but should be more for fat lines.
It was only ten dollars worth. I did a line yesterday night and then one this morning before work and again at 6:00 when I got off. So at midnight I had that final line and only did half. Too much?
Prices for meth varies, as does purity. A substance's worth is not very useful information.
I would recommend anyone that does binges on stims should have a digital jewellery scale and a basic BP/HR monitor, they cost about 20 bucks each and can greatly help you reduce the risk of overdoing it.
It would be much better if you were using a digital scale to weigh out every line, we can't know how pure the meth you have is, but at least you would know from previous experiences what effects you could expect from a given dose and you could tell us.
Also it is very possible to misjudge a quantity when eyeballing, if you don't use a scale at least use something as a reference, such as a cigarette or your phone's charging cable or the card you use to crush it into powder.
Remember to keep hydrated and if you can, eat something to keep your energy levels up, the quality of your high will improve, although for many it is very hard or impossible to eat while on stims.
In general, if you are in doubt don't take more not just for your safety but also because run the risk of spending the next few hours getting paranoid thoughts about your health.
