This will ask about several nootropics. The goal is to gather more reliable anecdata on which substances are most often found useful and what doses and schedules are most common and effective. Results will be made public when the survey is over.
If you've used a substance, please answer the questions about it. If you haven't, just skip the section. If you've only used modafinil, that means you'll be skipping all questions except the first and this survey will be very fast for you - but please take it anyway. Predicted completion time is 5 - 10 minutes.
For each substance, please rate your subjective experience on a scale of 0 to 10. 0 means a substance was totally useless, or had so many side effects you couldn't continue taking it. 1 - 4 means for subtle effects, maybe placebo but still useful. 5 - 9 means strong effects, definitely not placebo. 10 means life-changing. Please as far as possible rate each substance on its own merits - but if a substance only works when stacked with another substance and you're not sure what to do, mention that in the comments.
