Maybe it's just a really bad season, but I just started thyroid meds in December and this is the worst my allergies have been in a long time! But this is only my second year here in AZ and there was tons of rain earlier in the year, so it's a killer allergy season in general. But when I'm not sleepy from the benadryl (Allegra isn't doing anything for me and because of drug interactions I can't take any of the "D" drugs), I have so much more energy. Definitely check out the thyroid board, get tested, and if you know it's a problem, don't take no for an answer. Anyway, good luck to everybody.
