Does anyone know what might cause recurrent attacks of acute nausea (sometimes accompanied by d and or v)? I have had this for the last 24 hours and I had it about 4 weeks ago and about 7 weeks before that. It is never accompanied by a fever so its seems unlikely to be a bug (I always get fevers with a bug). The nausea is so bad I cannot upon my mouth and I also have vertigo.
Any ideas?
