Hi Steffie
Been away in the caravan for a few days so missed your post. Hope today finds you better.
I haven't had any problems with spikes etc these past few days but I don't tolerate these very humid and hot days and spend most afternoons in front of a fan with copious amounts of water - both internally and externally - thank goodness for retirment!
Seriously though, I have felt the heat a bit more than usual this year - it may be down to the Byetta - you can never really tell for sure whether a new drug is to blame for these things until you have been on them for a some while can you. The only thing I can suggest is to try and take your Byetta about 30 mins before you eat - it seems to be the optimum time for the best effect and might give you a better chance of levelling?
It is a lot cooler down here in Essex today, thank goodness - hope it is the same for you- take care xxx
