Personally I don't feel it much snorting it but I think that's because it's less euphoric.

From my experience in the short term you'll probably lose track of time easily, find yourself enticed doing something, anything, usually for long amounts of time. (Carpet surfing is popular to do at this time, as well as coloring, talking, and doing more meth.) I do not advise taking more meth for a week or so. This will help prevent addiction, as well as give you time to feel the effect as well as reflect. You'll find a boost of confidence, as well as being more social and often have more sex drive. If you pursue such you will likely go for much longer than normal.

May add more over time- cross faded as I write this.

Prepost Edit: Also lack of appetite
