I Google everything I take for interactions. I'm so bad, that each month that I fill the same two prescriptions that I've take for several years, I go on drug identifier.com and make sure the pharmacy didn't accidentally give me the wrong pills. It's crazy. I think it stems from a time almost twenty years ago when I took a vitamin with ginseng and for some reason, it made me very anxious. It's an awful phobia to have, because I suffer longer from colds and such simply because u will not take medicines. I know every person reacts different with meds, but I'd love any advice from members on meds that they've tried and that didn't cause the jitters or other uncomfortable side effects.
