Smoke more Meth and have sex/ mess around with my wife, listen to music, smoke more meth and buy as many downers as I can to level out.
Iv only did Meth a handful of times, not a fan of stims. If I want to get tweaked id rather be hallucinating to, thats where PEA's and ergoloids come into play for me since they have stimulant properties for me.
If someone is really spun the fuck out on some grade A Meth, I'm not talking about no D-amp either, you'll be able to tell but it's not like a tripping person unless they are in psychosis mode. They typically talk non-stop not really letting you speak much, fast/fidgeting movements, repetitive actions sometimes.
Its different for everyone and the smarter/veteran users know how to hide it better than other people ime(same with opiate and cannabis/ hash users ime).
