I have used Botox in that area and it has been very successful in lifting the brow.  It also helps in making the eye more symmetrical.  

Also lifting the frontalis muscle of the forehead can help soften the droop.

Yes its reasonable to get addition Botox after three months even if the original has not weaned off. But I don't recommend getting it any sooner than  that, from the last injection.  Even though it does not cause any harm, if you re inject too soon, the injector can end up giving less than you need and the effects will wean off sooner.

I do not recommend doing a home hair removal laser for two reasons, one they are not as strong in the penetration of the light and they can be very harmful if you are not a professional. I use the ICON-MaxR for hair removal in my office, and I have alot of success for all skin types. You need to be able to use a laser that can optimize the light technology to get good results.

The results that you have gotten is not due to excessive amount of Botox, the amount you got was very conservative.  The problem was the technique, the injection was too high or too lateral and missed you frontalis muscle.  The affects will soften over time, and since it was a small dose it should resolve sooner than three months. I would not expect it to get worse after the two week period.And unfortunately we can not reverse the effects at this time, you just need to wait.

Sleeping on your stomach or sides are not a good idea in general, because in the long run they cause more wrinkles, and the fatty tissues in your face to droop faster.  But after getting Botox or Dysport, there is no medical reason for the products to migrate.  The products are placed in the muscle that the injector was attempting to affect, and it will not diffuse to the surrounding tissue.
