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.
Typically, you take only 5 grams at a time. If you're in a loading phase, space your 5 gram servings evenly throughout the day. Competitive bodybuilders vary dramatically in the timing of their creatine consumption. Ideal times are before and after a workout! The reason for the varied timing of taking creatine is that it works almost any time of day. Just as it takes a week to load up in your system, one study showed it remained effective even for several weeks after stopping creatine. So take it when it's most convenient for you.
