Hi SMU,
I am really sorry that you are experiencing these rough start up effects.:( I know that it was a tough decision to even get to this point, and to have the bad s/e's...bah!
As the others mentioned, these should phase out soon...but for now, in additions to using OTC pain meds (not too many to avoid re-bound effect) you can try some
progressive muscle relaxation, to relieve any tension that you may be holding. This can be from anxiety itself...but also as a side effect (clenching of the jaw/upper body tension) of your meds, causing headaces.
Here is the link...give it a try and see if it helps.:)

Best wishes, and keep up the good work!
