Hi I should have been taking Metformin around about January this year, but have been too scared to start it. I tried getting Sugar down and did do so with a Ketosis diet - was 90 it is now 63. Over the last 3 months as I am going to sleep my legs suddenly and fast jerk jump, this also happens with my body it is like a hiccup reaction, and has got to the stage where it is happening right after the last jump within 1 to 2 seconds. I did have restless legs but this stopped and turned into the jumping. Also my body hurts, and my left elbow the bone was intensely hurting. So this week Tuesday I took my first metformin. That night my body never jumped and the pain seems to have gone. However, the second night the jumps have come back a bit. Any insight into any of this. I don't have the jerks when awake.
