I was recently diagnose too Type 2. I couldn't get on with Metformin felt nausea and tired all the time, I'm also on Methotrexate injection once a week for psoriasis, so that also makes me feel a bit nauseous. I've now been put on Gliclazide starting on 1 a day not much difference still feel nauseous everytime I get also acid stomach, but not as tired. My main worry is that this med causes weight gain and my aim is to lose Wight ot try are reverse T2 and get off the meds.
