No, your reception is fine. What you're experiencing is sound attenuation, the loss of energy from sound waves. Basically, attenuation is a damping of sound, an interruption that diminishes the volume and quality of the sound wave.
No, this is not necessary. A mere 3 grams of creatine per day for 28 days results in the same muscle content of creatine as that of a six day load program. Thus, if you wanted to get off creatine, it would take about a month to reach normal muscle stores.
The remainder of the creatine in your body comes from dietary sources. Good dietary sources of creatine include wild game, lean red meat and some fish including tuna, herring and salmon. Approximately 2 to 3 pounds of raw meat or fish contain the equivalent of 5 grams of pure creatine. Cooking will break down creatine, leaving it less available for your body to absorb it.
