Welcome to PC! You are not alone.
This place has helped me a great deal. One tip: (might work for you---or not),
I found moodtracker.com to be a good place to track my moods and keep a private journal. There is even a section where you can check off whether you took your meds or not to see if there's any patterns or "warning signs." Just a thought. I agree with the above, setting alarms help. I struggle with remembering sometimes. I never forget my Seroquel, or I can't sleep. Certain pills though, like Gabapentin 3x daily or Lamictal 2x daily gets me mixed up, when you're taking multiple prescriptions per day though.
