I am writing what exactly my medicine does : prothiaden is bio chem that lifts the soul plus makes brain sleep and puts an invisible curtain around the heart to make it comfortable , its effect is for some 8 hrs, alprex is an anti anxiety one but it works in tendom with the basic medicine. I am avoiding hi fi science related aspects as it are not needed by you. But the medicine antidep is not workable with me as it creates another problem when an unexplained uneasy feels are there.
