Waited for almost 2 hours before the doctor saw me, when I saw finally seen instead of prescribing me the medication I was looking for instead he made me take a more holistic route that I had already been doing for the past year. Even when I told him that, he still insisted I try for another month. I ended up going to a different doctor to prescribe the meds I was there for in the first place.

I was in there on Wednesday, March 27, 2024 at 3:30 pm and told him I had been vomiting since Saturday, March 23, 2024. I’ve called the office twice today and I’m still waiting on a response to help me stop vomiting. I’m concerned because no one had called me back nor have they contacted HEB to send the prescription. They hav ignored me and my calls totally.
