If you are desperate you have more viable and less destructive options than Chrystal Meth, Try reading about nootropics/racetams, there are also (depending on where you live) ADHD medications that are still Researche chemicals, such as ethylphenidate (Ritalin analog). So I would suggest a little internet shopping before buing something that might work but that would destroy your dopaminergic pattern and brain cells. To my opinion you should leave the Meth for if you dont find anything else that helps. ( If you want some other examples of what can replace Chrystal Meth, Send me a message about your needs and I will be happy to share the knowledge I have about psychoactive drugs.)
