Zyrtec helps me sleep...

Hey everyone!  I’ve hit 7 weeks and feeling improvements (Flu 20mg).  With that though, I wake up every night sometimes at 2am, 3am, or 4:30am and have a hard time falling back to sleep.  During that time I often experience anxiety.  Frustrating!  

However, when I take Zyrtec 10mg before I sleep, I’m able to sleep through the night till 6:30am+.   Wow!!!  Nice!!!

Has anyone experienced this?  

Any other thoughts and ideas on how to keep me from waking up?  I have tried melatonin with not much luck, and taking Zyrtec nightly might not be too healthy.

Thanks in advance!

Update:  It works for the most part but I can’t see taking Zyrtec long term.  Thus I’m still looking for options.  

All recommendations welcomed.
