Stark started ... waned

I suffer a little of permanent fatigue and am therefore often unfocused and have only moderate energy (despite a healthy diet). I then took 2 of the capsules and I have literally risen eyes! Energy, clarity and alertness as I have long had no more. Even better sleep I could.
Unfortunately, the blood pressure over the duration of intake has increased unpleasant, so I've taken just one capsule a day. The effect has, however, increasingly flattened and I after about 30 capsules feel that no effect is present. There seems to be a kind of habituation ... shame. Stark started and waned.
