Have through internet research Kick Speed found and bought a can of the same. I am excited about these tablets, pills, or what to call it and apply it, especially if it's in the evening or at night become much too late again and I early on must be fit again in the morning. With one or more cups of coffee beans ingested, is - at least for me - so after about 15 minutes the effect such a that caused this dizziness or feeling of insecurity by the lack of sleep does not stop. It is still a bit beside him, but can control it. The cycle is more stable and the behavior is normal, ie, as if it were not for the lack of sleep. My tests or rather self-tests have shown that I have to take at least three pills in order to obtain the effects described above. Less does nothing. In some forums I read that one should take more than 2 tablets never without jeopardizing its circulation. I would not deny that it might actually be my congenital hypertension that in my case this dose is not sufficient. However, if you now accept that one could take the stuff continuously and thus combat regular lack of sleep, let me tell you that it has at least a row no longer works for me after two sleepless nights, without increasing the dose, but what I have refrain from fear to jeopardize my health seriously. I decided it was rather healthy to sleep in. Conclusion: Recommended for occasional use either when the blood pressure again is bad in the basement, or if you take a night had to work and early morning fitness is required.
