(1) You are correct in that some of these things may be withdrawal symptoms. To be sure we're speaking the same language, dizziness
is a sense of feeling unsteady when everything else seems steady. Vertigo is when one seems steady but everything around them seems unsteady. Light-headedness is a faint feeling, and may present with dizziness, vertigo, or both. Typically, the mediation side effect is dizziness or light-headedness but not vertigo. Withdrawal, on the other hand, usually feels more like vertigo. So, the experience of dizziness you have in the morning could be withdrawal since presumably you have not had any for 10 hours or so. On a good (if we can call it that!) note, the experience of dizziness, though persistent, should not worsen.
(2) If you go down by 0.25 mg, it is hard to say how severe they will be, if present at all, but on the bright side they should not be any worse! And the waiting of a week is only a guideline - it is more important to gauge a person's withdrawal symptoms than the amount of time on a dose per se.
(3) Yes, the peak for each is usually 3-5 days following the dose reduction, although in rare cases it can last for or can peak up to 2 weeks later.
(4) They will continue to cause discomfort and annoyance, yes, but that should improve very much with time. And, as you go, the symptoms won't necessarily continue to be this severe. On that note, some of my patients who are very aggressive about wanting to get off of the medication make bigger cuts in it sooner. Why? heir rationale is that they are already miserable, and it can't get much more so, so why not go faster getting off and not deal with the withdrawal as long as a slow taper might have. Food for thought. :)
Hang in there! You WILL get through this ok! Glad to be of service. :)
