Glucose Test for second time!

Cr

So I had my first glucose test around 16 weeks due to there being diabetes in my family, straight after drinking the sugary drink I immediately threw it back up and then proceeded with a different blood test afterwards, which they said was fine (the test wasn’t as accurate though). So now I have to get my 28 weeks done in over a week and my anxiety levels are spiking, I can’t stand the drink at all and I’m scared of vomiting it back up again straight after 🥺 any tips to deal with it better or just try get through it?
