Hi, my Dh was recently diagnosed with type 2, & he's taking metaformin. Today he's really dizzy, & after he eats he gets cold, sweaty & a bit trembly. Last time (this am) I gave him some lemonade and a biscuit & he had a sleep & he felt a bit better, woke at 3pm blood glucose 17.6, urine glucose off the chart, and high ketones (not the highest, next one down). He ate about 4pm, now he's cold & sweaty & got back in the bed. Yesterday he was fine. The dr upped his metaformin from 1x2 to 2x2 per day yesterday. Should we make the trip to hospital (13 miles) or am I worrying needlessly (its a side effect - will pass, etc)??
