I used to be mosquitos' favourite meal, and I was also quite alergic to their bites: big part of me would swell up and look like a jelly for several days. During last year I started taking vitamin B complex, and large doses of vitamin C (about one gram before every meal or snack). This summer I noticed that mosquitos stayed away from me, even though they got my partner a few times. I am not sure if it was vitamin C, or the B complex. However, I noticed that when a few weeks ago I switched from the acidic version of vitamin C to the ascorbate version, some of the magic went away, and I got bitten again.
Then I made a wonderful discovery. I rubbed the bite mark with vinegar for about a minute, and the swelling and itching dissappeared after a few minutes. I used the unfiltered organic ACV, but I am not sure if the vinegar type mattered.
