The alkaloids in Kratom effect the brain similarly to an opiate, although it is not. It's effects are unique in that, at moderate or low doses it will generally be stimulating and euphoric. Based on hundreds of Kratom users feedback, it is not enough to impair normal functions such as socializing or working long hours. In fact, based on many interactions with active Kratom users, the feedback was that many use it as, not only an alternative to pain medication, but as an energy booster.
In higher doses Kratom will have sedating effects. Other, outside, factors can fluctuate these effects such as eating a large meal right before taking Kratom, body mass, general tolerance levels, etc. The active alkaloids in Kratom can have both stimulant and sedative effects.

The stimulant effects will cause the mind to be more alert, physical energy and increased libido, work for longer periods of time with accuracy, higher social ability and improved mood.

The effects of Kratom at low to moderate doses generally last 3 - 4 hours.
Also know as a euphoric or analgesic effect, in a higher dose you will be less sensitive to pain, feel more relaxed, have a general feeling of comfort, and may experience pleasant sleep patterns. Although rare, some have experienced itching or sweating. Your pupils may become dilated or small. Those who are predisposed to nausea with prescription pain medication may also experience this with Kratom. If nausea is experienced, lying down and relaxing may ease this symptom. The euphoric effects may cause you to appreciate things such as people, music or television programs that you normally would not. When done in combination with a relaxing environment with the goal of rest, you may find this to be a pleasant alternative to sleep aids. The effects of Kratom taken in higher doses generally last 5 - 6 hours. Kratom taken in higher doses generally last longer and have stronger effects. Many Kratom users have reported experiencing positive rest and feeling quite good the following day.
