Do the effects diminish after time? I used it for a while, and had the tingle feeling, flushed, and very intense dreams. These effects seemed to lessen over time. One other thing I noticed, or think I noticed, was that I was remembering details from past experiences that I normally would not. For example, names of people I had not seen in years, when I usually can't remember a name a few minutes after I meet someone. Any similar experiences?
