Noticeable effects of Kava?!

Noticeable effects of Kava?

I recently bought some Kava powder, and I would like to know if it is notiecable after I drink it. What will be noticeable?

Effects
The onset of a moderate potency kava drink is 20-30 minutes, with effects usually lasting for two hours. Effects can be felt up to eight hours after ingestion.

These effects of drinking kava, in order of sensation, are slight tongue and lip numbing caused by the contraction of the blood vessels in these areas (the lips and skin surrounding may appear unusually pale); mildly talkative and euphoric behavior; anxiolytic (calming) effects, sense of well-being, clear thinking; and relaxed muscles. Sleep is often restful and there are pronounced periods of sleepiness correlating to the amount and potency of Kava consumed. When drunk to excess, Kava can cause vomiting and a feeling of nausea that will subside usually by the end of the day after consumption. In Vanuatu, drinking strong kava is normally followed by a hot meal or tea. Meals consumed along with kava traditionally follow some time after the beverage so that the psychoactives are absorbed into the bloodstream more quickly.

A drink of high potency results in a faster onset with a lack of stimulation, somnolence, and then deep, dreamless sleep within 30 minutes. Unlike alcohol-induced sleep, after wakening the drinker does not experience any mental or physical after effects.
Heavy consumption of kava can produce dermatological effects ranging from light, red bumps; to heavy, scaly, ulcerous skin. Kava contains lactones that bind to skin proteins forming antigens which then lead to the allergic response. Discontinuation or reduction of consumption resolves the effects.It is reported that many people experience rather vivid dreams after consumption of kava. [1]

Kava can also be combined with coffee to produce kavajava, the effects of which are said to combine the most pleasant qualities of each.
