Phenylpiracetam might be an option. A little stimulating at first, but that aspect subsides with time. Noopept, alphaGPC, and Aniracetam would be a good stack for you. Unless of course you have epilepsy and/or high blood pressure. Could potentially help reverse brain damage from binge drinking and drug abuse. If you're a hard core smoker you might just be playing an expensive game of tug-of-war between neuro genesis and dain-bramage.
ill second the noopept! just make sure you are getting choline in your diet. i just started eating eggs more regularly and got enough that way personally
I have a good noopept for a very reasonable price. Just today I had around roughly 40 mg of it and it was awesome. I am a bit tolerant now, so forget me taking just 10 mg of noopept is enough. But still what a substance. I was having a good coding learning session and having decent conversation today. And boy I do not know about you guys, but I feel more horny on that stuff, can't help it.
