I hate the fucking comedown!!! ughhhhh it is the worst, when you have absolutely nothing, to bring you down off that shit! Some people say Adderall, has a way worse comedown... hell to the fuck no! I do both, have a script of Adderall and take it every AM, and I do coke, like maybe every other weekend, nowadays, but I always try to keep some of my clonazepam handy, which I am also scripted.. luckily! I have terrible anxiey issues as is, but when I throw a stimulant like coke or crack in the mix, I cannot NOT take some sort of downer when it wears off, that is the worst feeling ever, just sitting there, tweaking and feeling like you would rather die! mentally, it is one of the worst things to come off of to me! Adderall aint shit... at least not the dose I take, a relatively mild dose every AM 20mg a day of IR Adderall, and I feel it start to GRADUALLY wear off over time... coke, I shoot and smoke when its rocked up, and it comes on super fast, with a very nice, euphoric rush, and short but nice high... like 10 mins long.. after that, I must take at the very least 1mg of klonopin, because I have a massive tolerance to benzos, and 1mg aint shit to me.. if you don't have a tolerance for benzodiazepines like klonopin, valium, Xanax, Ativan(garbage benzo!), etc.. then start small, maybe 0.5mg of kpin or Xanax or 5mg of valium... don't bother with Ativan, it blows... ime.. but some say it works well for them, and its SUPPOSEDLY equal to taking 1mg of Xanax/klonopin, when you take 2mg of Ativan.. I believe?
Anyways, I feel your pain, and have felt it sooo many times.. those late night binges, getting yay at like 3am, doing it, because you are craving it soooo bad, and then regretting it when you don't sleep, and have work the next day... and then on top of that, having nothing more than Benadryl to help the comedown, which isn't a good helper at all.. The things I have found to work the best for a shitty ass, coke/crack comedown(they all are!) are benzos like I mentioned above, and others also mentioned before me, THC or any thing related to it like weed, hash, hash oil/wax concentrate/"shatter"... I also found opioids to help, but do NOT recommend it, it is a very dangerous combination, to mix opiates/opioids with coke of any form... I almost died from the combo of like 300mg of oxycodone and at least 1.5Gs of coke/crack one night, along with my daily dose of klonopin... It was some scary shit.. definitely overdosed, and almost was dead, unconscious on my floor when my friend just showed up at my house, and I thankfully had left the front door open for him, he saved my life.. so never do that! opioids, benzos, and cocaine is a very deadly combo not to be fucked with by anyone!!! I had a HUGE tolerance to all 3 drug classes, and still, it didn't matter at all, when you mix 3 totally different drugs like that together, your heart doesn't know what to do!
Anyways, just see if you can get some herb or a benzo and take one of those 2 to help.. I cant deal with cocaine otherwise, and don't bother doing it, if I don't have something to bring me down.. NEVER AGAIN will I let myself do that! Good luck, be safe.. if you feel as if your going to OD or something, def seek medical attention at the ER, like others stated already..
