Swim found that adderall + coke was too potent a combination to be of any real use academically.
Focalin XR followed by a small line of coke after it was wearing down was useful. The coke brought back some of the focus of the focalin and keep swim motivated / energized. Wouldn't recommend doing more than one line per hour, and less is even better. Otherwise you just start doing lines which will inevitably end up being counterproductive.
Ok, so swim tried this combination once again, simply because he needed stimulation to do work and didn't have much to use, and also to fully satisfy any remaining curiosities swim had about the combination. As this is an upper+upper combo, however, one should take extreme caution if they intend on trying it, and swim would recommend against combining adderall and coke to anyone wishing to try it. That said, lets move on to the report.
Swim took 10mg of adderall and complemented it with 2 grams of piracetam mixed with an energy drink as well as 600mg choline. Swim has been takin piracetam on a regular basis since early January, though when he takes stimulants such as adderall he will often take some extra piracetam to supplement.
Swim did a medium-large line of cocaine right after ingesting the adderall to help get him started quicker. He then took more lines at 15 and 30 min past ingestion. After that swim stopped keeping track of when exactly he was doing lines and instead would check his pulse to see how it was doing. Swim's heartrate reached a max of around 140 during the entire experience, and when his pulse got up to that point swim would refrain from any further snorting until his heart slowed down to a more normal pace. It did seem a bit easy to raise his heartrate though, so the sizes of the lines decreased as time went on.
Overall swim felt that the combination of cocaine and adderall was far more conducive to studying than cocaine alone, but didn't have many other benefits that swim could see. One nice aspect of the combo was that when the coke high wore off swim didn't feel like he had crashed at all, but just returned to the level of adderall stimulation. The lines seemed to hit swim stronger than they would have if he wasnt on adderall, but they also seemed to take longer to kick in than usual. Swim got a bit speedy/tweaky while trying this combo, but his focus sustained itself nicely. A downside was that right after doing a line swim would lose some of the focus for llittle bit, especially as he felt the urge to have a cigarette after each line which made him smoke more than he would have on adderall alone. As the adderall wore off the coke didn't work as well (could be rapid tolerance factor) and the comedown was more noticeable, though it still wasn't as bad as coke can be by itself. Swim felt pretty decent after he could no longer feel the drugs' effects, but he could tell that the combination was a bit strenuous for his body, especially his cardiovascular system.
The experiment of combining adderall and cocaine surpised swim somewhat, especially the positive aspects of the experience. Still, swim doesn't feel completely comfortable with mixing the two substances, and I don't think he will try this combination again, regardless of the circumstances. Its simply not worth the risk of combining for the amount of increased benefit received.
