sleep patterns

I've been taking my meds on a regular schedule...What I'm noticing lately and I think it's because of the amount of stress and anxiety I have on my plate right now (which I'm handling quite well, but may be affecting my sleep patterns).. .is the following...

5:00-6:30 am (closer to 6:30 am on my days off...)

100 mg Topamax
300 mg Wellbutrin
pill for acid reflux
B12

8:30-10:00 pm

300 mg Topamax

I'm thinking of pushing the Topamax to closer to maybe 6 or 7 to see if it won't make me more sleepy earlier in the evening because I'm finding myself laying in bed, my body wore our but my brain and eyeballs like wired and ready to go...

Then in the morning... I'm waking up ten to thirty minutes prior to my alarm going off... so getting up at like 4:30 in the morning... is RIDICULOUS, especially on days when you don't have work... AND NOT BEING ABLE TO GO BACK TO SLEEP EVEN MORE SO... but then needing a nap a few hours later and not being able to get one is crucial...

I have to go back to the doctor next Monday... she wanted to give me something to help me sleep then, but I didn't want it, if I tell her this she is probably going to insist... the thing is I'm still getting enough sleep, it's just weird... like right now I'm yawning and my body feels tired and my mind feels like it didn't get enough sleep because the stressors in my life right now are causing really vivid awful dreams so I'm not getting that normal coma like sleep that I get on these meds... and its been like that for a week now... I'm sure I'll figure it out...
