I am too tired to do anything all the time. My husband was away on a job for a week and I didn't have to move but since he is back I want to have a "normal life" after 10 years of this DD. Provigil makes me nervous. Are there different strenghts? I can take a caffeine pill if I absolutely have to stay awake (like when I watch my 3 year old grandaughter one day a week) I can only do that when my husband is here. But the next day after a caffeine pill is really a bummer. My doctor said my diabetes II and having too much calcium in my blood would make me tired. Who knew you could have too much calcium? I try to keep my diabetes under control but it is hard to know what to eat when you don't have the energy to cook. I don't like meat very much and I hate vegetables.I do drink V-8. I'm taking magnesium and L-carnite and it has helped with the brain fog but don't know how much magnesium to take or what form. Would NADH or fish oil help? I KNOW I am not tired or sleepy but my brain TELLS me I am exhausted.
