Ah I know nothing about lantus as I'm on Tresiba, I know right, I had 4 sweets this time waited 20 mins and was still below 4 so had another 1 and 20 mins and back up to 4.7 by tea I was 11.something so my meter suggested a 2 unit correction but I only took 1 by bed I was down to 8.9 which prompted a correction which I didn't take as didn't feel comfortable doing it, woke up on 7.4 so had to take a correction with breakfast, now down to 4.6 before my dinner so I'm panicking again haha, feel very paranoid today so did a 1,2,3 and 4.5 hour test after breakfast and now I'm going to be doing a 1,1.5 and at least a 2 hour test after lunch in the hope that if I catch myself going low I can have a biscuit or something to try and stop it x
