I get a hoarse voice stright away after any meal, also when my voice is ok not hoarse etc the vocal cords and voice gets tired, no strength after5 min?

Hoarseness . After meal hoarseness sounds a lot like reflux to me. Also throughout the day the voice will get weaker if you are refluxing throughout the day. I would take Prilosec once a day one hour before breakfast. If you are still hoarse try taking it before supper as well. Eat low acid foods. Check online for a list. Good luck. If you are still hoarse see the ENT doctor.
