I'm on 300mg xl welbutrin. Started feeling anxious and Dr placed me on Buspar 5mg twice a day

-10/2 
- lost balance slightly twice. Both around 30-45 minutes of taking 5mg.
-second dose around 3pm. headache around 6.
10/4 headache at 800 after 0630 morning dose. 
-have been noticing mild brain zaps. Not like before-they were like wham! These are very subtle but there and numerous. 
-10/5~10/9
1. angry feelings about stuff. Keep ruminating on events, so much that it's hard to calm down. I can but it takes a bit and then it's hard not to start back up on the ruminating again. 
2. Some pressure in head about an hour to 3 hours after taking 
3. Tinnitus has ramped up from 1.5 to a 3..
4. Zaps are still minor but happening. 
5. Continue to have small balance losses. Not many. 2~3 times a day. This could be come problematic during work events.

Do these sides go away eventually? I really want to give it a chance but damn it's hard. Should I ask for an increase? Should I stop? I know we're all snowflakes and each medicine we take affects us differently. But any of your experiences would be interesting to read.
