Looking for some advice from advance practioners

So I have been practicing moving my energy now for a number of years. But have issues turning it off. I can create heat, make areas of my body vibrate, and have a static feeling like little bolts of electricity shooting of my hairs just by thinking about it . It creates almost a euphoric effect. I think it is due in part because more adrenaline is released while moving the energy around the body since your pituitary gland becomes more active. This explains the tingles and random goosebumps I get sometimes.

Now it’s all fine and dandy, but once you run out of juice the rebound sucks. While moving and gathering energy in your body you feel energized, but after you want to pass out. In addition, I have been having weird electrical feelings around my heart. I went to see a doctor a year ago and they couldn't find anything wrong.

Do any of you feel the after effects and how do you deal with it to minimize the rebound as I call it.
