We were staying at Le Lagon when we here hit with an awful gastro bug.It can last from 12hrs to 3 days. Apparently it is around the island It was advertised in the Le Lagon newsletter We were traveling with 41 guests (all staying at different place) and so far I know of 15 people getting it. We packed with us Buscopan and Imodium. All 3 of us got it and unfortunately I didn't bring enough tablets and they are approx 2000Vt to buy around $30. Other people at the resort also had had it that I talked to and a couple also had it on the plane going home (poor things) If I has know I would have packed a glen20 room spray and a couple of extra boxes of tablets.
All the locals tell you to drink Sprite or tonic water when you get it. i think I did help a little
