Are there no medicinal treatments without drowsy side effects?
The answer to that is "yes", but there are a few provisos !
Non-medical treatment should ALWAYS be considered first, if at all possible. I have commented on here before that too many folk "reach for a pill" far too readily these days ! However, if other means do not control, and the situation is distressing, one might consider MOTILIUM (that's a trade-name , chemical name is
domperidone ).
It is prescription-only in the UK, so you'd need to discuss getting it with your GP, cannot just buy from a chemist. This suggestion from me is ONLY FOR ADULTS ! I could not condone children being given medication like this for non-medical and recreational reasons.
But in the right circumstances it has a very powerful anti-emetic effect without any of the sedative side effects of the phenothiazines. My (adult) daughter used it very successfully in the early days after I got my PPL. She doesn't need it now !
