I have 2dc, 5 and 2. I am constantly tired and most days after the initial breakfast sugar boost I just feel rubbish. Groggy and heavy feeling around the eyes and head, headachy etc. Nothing painful but just generally feeling rubbish. I take antidepressants 20mg which help me get by. I've had a difficult few years. I don't want to take a higher dose and don't think I need to. I don't think I'm depressed but years of interrupted sleep has got to me. Could it be sugar related? Any advice appreciated.
