Hi welcome to Health care magic forum.
Thanks for calling H.C.M.F.
According to your description it appears to be due to vertigo
, it could be due to hypertension
, diabetis, internal ear infection
etc. among them internal ear effect is is most likely cause.
It may not be of gastric origin because no motions and it has recurred after 3days and no symptoms in between.
I advise you to consult an E.N.T.surgeon for diagnosis and treatment. You may have to take M.R.I. besides other routine tests for confermation .
Wishing for a quick recovery, and no recurance.
