Reducing medication?

Type of diabetes
Type 2
I am a diabetic and also have schizophrenia. My sleep got disturbed some years back and my diabetic medication was increased to include metformin gliclazide and plioglitazone

Recently I managed to improve my sleep considerably and this also caused my diabetes to improve. Gp recommended I reduce my gliclazide so I did. My diabetes was still low then there was shortage of plioglitazone so doctor recommended that I try stopping it but now my diabetes is shooting up a bit 7-13 range

Has anybody else have experience with reducing medication. Is this spike temporary or I should increase my medication again. Maybe my body got used to plioglitazone and stopping it completely spiked my readings a bit temporarily. I was fine when I reduced gliclazide

Is anybody able to advise and has experience with reducing medication though I am visiting my go soon
