OK - I'm going to be the 'doom and gloomer' with this discussion.
This is an excellent discussion about cognition and testing by two real pros! However, this begs the issue since this would be anecdotal information and not valid clinical data that would stand the scrutiny of a good RCT.
Often the question about diving or not on medications should be about the underlying condition for which the drugs are being given.
Fibromyalgia comes and goes, migrates, gets better and worse and is a difficult condition to treat and to try to get a baseline of severity. This needs to be done, however, as you need to know as much as possible the degree and location of your pain for comparison in case of a decompression accident. You should write down all signs and symptoms that are present immediately before diving so that you won't have the tendency to blame a painful shoulder or knee on the disease, rather than DCS.
The seizure causing effect of Buproprion (Wellbutrin, Zyban) (1% across the board) is definitely dose related in individuals with predisposing factors,with seizures occurring in only approximately 0.4% of patients receiving dosages not exceeding 450 mg daily of bupropion as conventional tablets.
This is a small risk; but you must take into consideration the fact that a seizure underwater has almost 100% risk of death from drowning or severe injury from gas embolism if rescued from depth without breathing.
