I have been suffering with extreme tiredness now for the past couple of years, had lots of tests at doctors nothing seems to be wrong! I have been giving various antidepressants over the course of time as keep being told this must be problem. However, after taking these no difference at all , I feel quite happy in myself at the moment and not at all depressed apart from feeling so tired makes me feel low because I used to be very active. I am only 35 years old otherwise fit not overweight, and eat quite a good diet. I always am in bed by 7 - 8pm and wake around 7.30 still feeling exhausted and more often than not sleep for a good 3 hours during day! Thank goodness I dont work, but I really do want to get a job but am worried about keeping awake!Are there any prescription medicines available to give me some energy and keep me more awake? I feel my life is passing me by and want to enjoy my children and have the energy to do this. Yours hopefully helen riley.
