My two cents .... I traveled to get the meds and started as soon as I got them. No problems for me.
Many people, myself included, have reported an energy bump early in treatment ... seems to be roughly the second through fourth or fifth week. Imagine being on vacation while you're experiencing an energy boost!
There is, however, a very frequent reporting, again myself included, of various forms of insomnia about that same time frame. For most it is a tendency to wake early (like BOOM ... I'm wide awake!) and not be able to get back to sleep again until evening.
Personally, I'd go!
