Hi guys. I've been diabetic for 19 years , doing well, little background retinopathy but nothing major to worry about ( I hope!) I'm now 36. My partner is also type 1 ( randomly as well - ha ) he's on Levemir. So , I tried the new Toujeo insulin ... I was on Lantus before. Like others I had the lows in the night - 18 units caused a low, 17 units too high - seriously it was the bug bear of my life!!! Try Toujeo he said ( the specialist) oh my god I loved Toujeo ... for like 3 months. Then I started with major highs. I am talking going to bed at 4.8 and waking up at 20 in the middle of the night for the last five days. What the hell, what the hell. Lantus never did this to me even though it's still ****** me off I tried everything - it must be a bad pen, I must change injection sites, what have I eaten, am I sick?? , I must exercise more ?? Jesus people - high levels are F ing horrendous and I felt sick as a pig - it's never happened to me for a prolonged period ( don't get me wrong I go up to 15-ish often before correcting , but that doesn't seem to affect me as much) . I knew something was wrong and I started to worry that after 19 years of pretty stable management it was my time.... Low carb Day, regular shots, levels were still soaring at night and late afternoon. So I have gone back to Lantus... It's day one let's see what happens. However, I know it's a new insulin and there's not much research on the outcomes but my conclusion is it's pretty pretty ****. Google tells me I am not the only person who has experienced this. This panics me for newbies diagnosed who they put on it from the outset?! I Would be really interested in other people's experiences. I will feed back to my consultant in January but I'm quite worried about the whole Toujeo situation!!! Who can we tell???? Last night my partner woke me up at 3am having a 2.2 low and there I was at 20..... we live in a crazy crazy world!
