I live in England in a house with single glazed windows. From November to February it is usually necessary to go round the house and wipe condensation from the windows to prevent cumulative damage to the frames. I also make myself some coffee in the morning. Over the weeks I noticed that I had no problems if I made the coffee after doing the windows. If I made the coffee first I experienced uncertainty during the various stages of the process. I was taking 1000 IU of vitamin D every eight hours. I realised that the tablet I was taking before I went to bed was no longer lasting through the night. I was not too concerned though as the symptoms were mild and disappeared when the morning tablet kicked in.
