I took a car trip and thought I getting motion sickness (never had before)..nausea..headache and some lightheadedness. This feeling stayed with me during the trip...10 days. I still have feeling of nausea and a headache..nothing like a migrane..just dull ache. Every now and then..it subsides..but for the most part, the nausea is ever present and the headache is there. I have taken tylenol...not much difference in ache...taken pepto bismal and it does seem to help the nausea, but I hate to take it very long!! Any suggestions! Thanks.
