Hope you are feeling better soon. This time of year, even before ever having had Lyme to contend with, I start taking a blend of elderberry and zinc by NOW Foods, also containing extra C, bee propolis, and slippery elm bark. It's a chewable tablet, and tastes sort of pleasant. Also Vital Adapt, by Natura. It comes in tinture or capsule. I just add the tincture to my tea, but I by the capsules for my family who don't drink tea. When I start to feel any scratchiness or swelling in my throat, I take grapefruit seed extract. It tastes awful, but has kicked many germ butts for me, and kept me from getting a full blown cold.
