I don't take any though I have given it a try many ears ago. I personally prefer alprazolam (aka xanax) now - it helps great with my ADHD too (especially in combination with piracetam and sunifiram) and is much safer as long a you don't abuse it (by taking high doses or mixing it with alcohol). Anyway, it is important to mention that FDA-approved meth from a licensed pharmacist costs are insane, street meth of the same or better purity is more affordable by orders of magnitude. There is also no such thing as "approved meth from a licensed pharmacist" outside the USA unfortunately so if you need it and go abroad that's a problem (I wouldn't even risk having it in my luggage).
