Hello everybody i hope everyone had a good xmas and is still sane during the holiday season .
I've just came off a 2 week break from my routine and when i took  my start up dosage of sp and fen almost instantly my sinus started to
become plugged . I really never noticed it before, ( had a stuffy head since october)  thats when i started adding fen just thought it was the season.
Has anyone else experienced sinus issues while using fen?

I’m on a 2.5 week break & I'm having sinus issues. But I’m attributing mine to the dry air. Plus, I bought a dehumidifier for the basement, and it’s doing a bang-up job. I could be wrong, but I think my issues are humidity related. Thx
