I would lower your dose for if you are not getting enough sleep then how do you think you are going to do in the gym? I ran into the same problem and to lower my dosage on the same gear you are on and after I did that I felt fantastic and was able to perform even better in the gym than ever! So...
To be honest I took it once and I didn't find that it didn't do much for me, it must have ben a bad batch. I wonder if that is what happened, maybe you could PM me and give me some info and some prices on the particular gear.
