Meds confusion and experiences

I am a recently diagnosed Type2 (1 month ago) and I am on a slew of meds: Metformin 500mg x 2, Lisinopril 5mg x 1, Pioglitazone Hydrochlorid 45mg x 1. I was on Metformin 500mg x 3 which was causing severe diarrhea so the doc took me down to 2 each day and added the Pioglitazone.

How is everyone dealing with this medication mix? Anything I need to be aware of? Things to look out for like other side affects?

The mix seems to be working along with a good diet but my daily levels are still not down anywhere they need to be (avg 200).

Thoughts, suggest, comments welcomed!
