No, what you're experiencing now will subside as you learn when to
take the meds and when your system is telling you that you have reached the point that you are fully functioning at the level of med you're taking.
I began with 25 mg., increasing to 50 mg. then to 100 mg. to build to a standard dosage. With diet changes that reduced too much acid food and adding more alkaline- reacting foods, e.g., cutting out coffee, tea,
chocolate, some dairy products, and white flour products, I have been able to function well with just 25 mg of Lamictal. If I have an overly
stressful time, I may increase to 50 mg. for a short period until the
stress has diminished (usually within 3 or 4 days).
It really isn't an all-or-nothing form of medication. It is, however, one of the best medications I've ever taken, especially permitting me to make diet changes that improve over-all functioning. I've written about the need for diet changes in using medications, and I think it
may be located on about page 3 or 4 on the forum called "The Diet
Recommendations You Requested: A Repeat". Some of those may
be helpful for you if you wish to pursue that.
Again, I'm not a doctor; I've just lived through what you're experiencing and hope you will rely heavily on your doctor's expertise.
