Lamictal Daydream, Trouble Concentrating, Better Tomorrow, I Am So Tired, Nyquil

I am on 300mg for bipolar. I am having trouble concentrating, remembering (i forget what i'm doing while i am doing it!), I often worry about driving-just don't feel like i can focus well enough-riding down the road thinking "hope i know what i'm doing". It is like i daydream constantly with periods of not daydreaming. I feel pretty cheerful and not having any real emotional problems, but the physical problems are a mess. I am so tired that i feel like every single day is a "well i'm sick today, i'll give myself a break, maybe i'll feel better tomorrow". i do have better days sometimes, but for the most part, i feel kind of useless-not "useless" like i'm depressed-i mean "useless" like i get nothing done and it takes me two hours to get some lunch for myself and my three-yr-old child, and i mostly sit around because i'm "taking a break" and my legs are so sore or i have a headache or i feel shaky, or nauseated - each day, i feel so sleepy i am desperate for my husband to get home to care for my daughter (and me)-it feels like i took NyQuil or Benadryl or something! So, i am literally pretty useless. It's such a shame. I can't find a medicine to help me cope, it is always a trade-off...and going on and off them to try another is a nightmare. At least, right now, it is just a daydream...
