This is a strange substance for me. It's a love/hate thing for sure. The weird part though is that the hate outweighs the love significantly and yet I still go back for more every now and then. I find it extremely hard to stop dosing, and the more I dose the worse I feel. I've experienced this many times and said to myself that I wouldn't use it again because it's just not good for me... but after a week or a month away I'll suddenly get the urge to have a bit (which turns into a lot).
I envy people who get long lasting stimulation which is enjoyable from ethyl.
I get a very strong and euphoric intial rush (whether I snort or eat) which is very short lived. An hour or so. Then the experience turns quite suddenly and I feel anxious and worried that the good feeling is wearing off and I know that if I have more, I will compound the problem, but damned if I can resist redosing. The second dose was sometimes, but not always, bring back some of the good feelings, but basically every dose after that brings only increased physiological side-effects. I get increasingly jittery, sweaty, and unfocused. I'll feel shit and want it to end, but then, as if I've lost all self control and judgement, I'll find myself saying "do another line, and make it a really big one, and then you'll be more focused and ready to come down". Makes no sense, but I do it anyway.
The only good experiences I've had with ethyl were when I was already quite sedated on opiates and/or benzos, and then mixed a fairly small quantity (say 30-50mg) into a glass of water and sipped the water SLOWLY over a course of 30 minutes or more. The gradual onset seems much more manageable and results in a more gradual come down, whcih lessens the likelyhood of excessive redosing.
Anyway, that's my experience with ethyl. This is not a recommendation for how to use ethylphenidate. It's different for everyone and as with everything you need to start small and give it time before try more. Less is more with this one. LArge doses just get really physically uncomfortable and the side effects are fucking annoying: can't eat, can't sleep, can't relax or sit still.
