Re: f*ck this ****, I need energy to train..
Or you can just eat normal food. Trust me. I started out like "oooh I need energy to go to work, why don't I take something." Slippery slope, expensive, and makes you reliant on substances for your motivation, which is dangerous imo and definitely harmful to your mindset in the long run.
I recommend eating more. I just put back on about 15lb that I had worked so hard/done so much drugs to take off, and I look worse but feel way better and am more motivated.
