Hi. I have been type one for 3 years and just started some regular exercise, road cycling of all things. what I would like is some info advice please. I have had mixed results when preparing to ride, for instance 1 hrs moderate exercise usually increases my levels, thats fine I have this sorted. well I thought I did. sugars prior to cycle 7.5 I then cycled 20 miles to work 1hr 7min, sugars up to 14, had something to eat insulin all good 2 hrs later. then cycled home 20 miles after 8 hrs of work sugars 5. excellent. so next day I took my sugars in the morning 7 had something to eat and gave 50% dose of insulin, cycle 20 miles to work sugars 4 had food and all good, cycled home took my sugars 7.5 cycled home and sugars 3.8 and they stayed like this for 2hrs I took fast acting glucose as directed by my monitor but nothing changed them, I got up to cycle today sugars 5.5 yipeeeee got it sorted, had breakfast decided my legs are sore no cycling today but my sugars have been low all day 5 then 3.8 I have of course been adding food where I need it but something does not feel right I feel spaced out like I am HYPER buy I am not, I am eating food and not having to use insulin....... weird, will this catch up with me with super high readings at some point. When I left work my sugars were 7. 30 min drive home and checked again 5, then they went to 3.8 again gave glucose and they stayed the same for about an hour no exercise either today!!!!! whats going on am I going to have to learn all over again or shall I stop exercising and make it easy on myself!!! When I do not use insulin I feel tired even though my levels are 3.8 to 5.5 or even when they are at 6 constant, Can I exercise and eat without using insulin and be ok, but how do I get the energy because it is definitely different exercising and eating without insulin to eating and insulin then exercising, help!!
