I've accidentally missed several doses of my wellbutrin and have taken my tegretol and the one dose of wellbutrin I usually remember at weird times during the past week. Consequences: headache,
really fast cycling, deeper depression. So now I'm really going to try to take my meds and take them on time.
My pdoc just switched me to one 300 mg wellbutrin XL tablet, so I won't have to remember to take the second 150 mg dose in the afternoon that I often forget. I can foresee this helping a lot.

This may also be a good idea for anyone who consistently misses a midday dose of a med, provided that an extended-release form of that medication is available in the right dosage.
