1: To properly ground using the golden roots method, do I want to imagine equal exchange between the ground and myself? And how should I know how much energy to release? ( I can't necessarily feel just how much energy I have stored, so it becomes a problem )
If your using the golden roots method I remember, a good way to measure it is by breathing. Inhale as you bring pure energy in through the roots, exhale as you release the harmful energy or quality you need to Ground.
My personal favorite method if Grounding is to do breathing alone. Inhale for four seconds, exhale for eight seconds, concentrating or visualizing on relaxing and/or releasing the excess energy or psycho-energetic quality (nervousness, anxiety, fear, anger, ect) that is disturbing you. With enough practice with either method, you can eventually learn to Ground with one breath, and with even more practice it will only take a single thought.
2: Can I actually make myself physically sick doing this? I ask because I felt like i might actually get sick if I do that again, and want to know if I'm doing it wrong.
Charging, either by Generation or Accumulation, puts a certain amount of stress on your energy system. It's like stretching your physical body, or weight lifting, or running, or anything similar. Doing it to a certain extent is healthy, and beyond that limit it gets dangerous. This is why it's usually recommended that your ability to sense energy is VERY good, and that you can ground very quickly and easily, before you ever even think about serious practice with Charging.
3: Based on what I've said, are there any tips on energy gathering and manipulation an experienced psion can give me to help me learn to feel and deal with energy?
Stick with Grounding and expanding your ability to Sense energy, then after a few weeks or months when you can Sense and Ground comfortably you'll be able to learn Charging without much difficulty.
