S.,
I don't know if this could be from your increase...or if it could just be attributed to anxiety...
...as I have had profound chills from anxiety! I can go either way actually...from hot to frozen and shivering easily during stressful times.
Night time is especially troublesome as my metabolism drops...and sometimes I just can't get warmed up again.
I hope this is a temporary thing that phases out for you!
How are things otherwise? Good I hope!
Hang in there until you reach your dosage goal.
