prevention help?

[Jessekig Baka]

hello friends, hello friends, unfortunately I've been getting quite a few more of these episodes lately, and I'm pretty sure it's from the extended use of a computer monitor. would anybody happen to know a good preventative? I really cannot avoid having to stay in front of the monitor for long periods and this is really starting to get troublesome.
I already take a daily regiment of vitamin supplements as well as trying to stay hydrated and not have a lot of sugar or treats.
I do allow myself a can or two of Sprite in the evenings, maybe I'll try not doing that for a few days or weeks and see if that helps. Appreciate any advice thanks.
