Tried the vitamin thing & it didn't work for me. Yes, I took the vitamins for several months before I went to JA. The bugs love me. I have tried lots of products (not the flea collars on the ankles!). Finally found out what works for me - Off Deep Woods w/DEET. I spray my legs & feet before I go out in the morning & reapply several times during the day - especially at night. I only got 1 bite at Christmas & no bites in February! My husband never gets bitten, me, those buggers eat me alive if I don't use Off Deep Woods.
