^^ yeah you need to dose at night before bed or you get tired. Prami acts more on the d3 receptor than caber. This makes it more effective in the area of sexual function. D3 receptor is crucial for male sexual function. The both also act on d2 receptors as well. Thats why some get nausea at first with prami. The area of the brain responsible for vomiting is loaded with d2 receptors. prami agonizes thee receptors..
All in all i like liquid prami the best. Ease of dosage , VERY effective , helps me get to sleep.
