|I'm due for work up.|
I am sensitive to all things that change my historic "feelings"
I lost weight, summer came and I'd break a sweat walking the dog. This was after a cold winter when my MD raised my thyroid meds as I was feeling colder than usual. The temperature thing is a pretty easy tell. If you are on a med that lowers bp and you pass out....good chance that if you lost weight, you are taking too much.
There is always a "range of dose" that affects your body. No dose is perfect but not all meds can be reduced.
If I dropped to the floor, I'd get a check up asap.
