I've done it for years. The reason it is not recommended for people with diabetes to apply lotion or cream between toes is because it is often times difficult for the cream to dry efficiently between the toes due to the closeness. Sometimes my feet feel like someone has set them on fire and they are doing a slow burn. If not, I would suggest you discuss this with your physician and ask about the results of your last laboratory tests. The symptoms could also be related to a neurological problem, please consult with your physician so your symptoms can be properly diagnosed.
Alcohol is treated by the liver as a toxic substance.
One of the functions of the liver is to rid the body of toxins. The liver also converts stored glycogen to glucose for circulation in the blood stream, which causes blood glucose levels to rise. If your liver is getting rid of the alcohol less glycogen is converted to glucose, so your blood glucose level is not as high. That is why we caution people with diabetes to drink with food and drink in moderation. It sounds like you have a family history of Type 2 diabetes.
