You could see if you can get a few samples of recreate, I know its the 'ultimate fatburner', but besides that, it gave me some nice clean, non stim energy, and I dont think it will bother your sleep if you take it say before 6pm. I dont know if USP offers samples, but I read a thread that vitamin shop had some usp samples. Just a thought, dont know if its worth your time to look into, the product is great, but Im not sure if its what you are looking for, then again, it might solve all your problems.
