Everyone's metabolism and chemistry is different, so I don't know how helpful anecdotal examples are. I've been on Wellbutrin for nearly twenty years and vary my dose between 300-600mg and i have occasionally moved all the way up to 750--way above recommended dosing. I also take abilify, varying 2-6mg--it is a dopamine agonist and i take synthetic thyroid and i am prescribed vyvanse 60mg(an amphetamine). Over the twenty years I have been on Wellbutrin, I have gone long periods where I drank excessively heavily on a daily basis, long periods of shooting coke and I would push that to the very limit--we're talking stupid gluttony. I spent almost ten years smoking crack with the same deal, trying to get as high as possible for as long as possible. In recent years, I supplement my prescribed amphetamines with blackmarket Adderall and Dexedrine--I usually buy 60-120 x 30mg XR. I supplement all that with fairly regular heavy use of meth, which I have variously shot, eaten, plugged, and smoked. I've taken my fair share of knocks on my head--cycling accidents, twice hit by a car, fell off a balcony, got my head done in by baseball bat. All of that terrible display of disregard for my health and the danger of seizures and other than twice, severely ODing on cocaine, I've never had any trouble with seizures. and the two times on cocaine, when i came out of the seizure, I just resumed using. Seizures are a risk, but it is not at all common. I always check online for contraindications too, because my doc isn't great with her drug knowledge--most of what she gives me is contraindicated!
I will say, wellbutrin is a very powerful, very serious drug. I would advise anyone thinking of going on it that it better be to treat very serious symptoms. I haven't been able to get off of it, and it has made marked changes in my personality. For your needs, Wellbutrin does generally have a very activating effect on most people. greater energy and a greater intrinsic motivation to do things. I went from lethargy and idleness with any tasks seeming insurmountable to always ready to go, engaged, immersed, happy to be busy. I think over the years, the hard living, the prescribed medications and the illicit substances have worn out chemical systems inside me, as nowadays I can be jacked to the gills on everything and barely functioning at the level of a hangover sunday.
With wellbutrin, I would also suggest to be mindful of your moods. Maybe it is the norepinephrine, but it can increase anger and aggression. I become angry much easier over less(and can't always tell its less because of the volume of feeling inside), and it takes a lot longer for anger to subside, for adrenalin to subside. that increase in baseline level chemistry can lead to rumination, obsessing, distorted thinking about conflicts. I have had to kind of have a constant CBT program running in my head advising me to ignore a lot of the signals my body sends me. I've seen this side effect in many others, in some quite pronounced and they could not continue taking it. For years, neither doctors nor the literature would admit to this side effect, they would tell me that is nonsense, and that if anything it should make me more relaxed and patient. They tend to admit it now, even if they minimize it some. The increase in aggression wasn't all bad, I was somewhat passive before. But, the emotional volatility and changes in perception are why i keep trying to get off of it.
I hope wellbutrin helps get you more activated and active. It is very good at that--and you don't feel buzzy or like you are drugged--you just feel great. It doesn't take weeks either to start producing effects. More like a day or two.
