precription eyeglasses make me feel tall

My old Rx was
R Sph +0.25 Cyl -1.50 Axis 180
L Sph  -0.50 Cyl -1.25 Axis 180

My new Rx is
OD Sph -0.25 Cyl -1.50 Axis 003
OS Sph -0.75 Cyl -1.50 Axis 177

I've been wearing my new glasses for 2 weeks now but seem to have an odd sensation of being taller which probably sounds weird, it certainly feels it and is also making me feel a little of balance and queasy. I had hoped any adjustment I needed for these glasses would be over now and things would settle down. Should I go back or is this normal considering the change in prescription?
I would be very grateful for any suggestions.

Dear Shaz69,

I would recommend that you seek the care of your eyeMD to determine whether there is a reason for the distortion you experience with the new glasses.  The difference in prescription is small but the adjustment of the optical center, refractive index of the lenses, base curve of the lens may be the reasons why the prescription may cause difficulty in adjusting.
