I understand completely that you have so many unanswered questions in your head and I totally understand how dreadful the sweating is.
The thing is that both wellbutrin and prozac will cause excessive sweating. It doesn't always happen as soon as you start taking them, it can come on well down the line.
I am thinking that you may have been OK on prozac alone but that the introduction of wellbutrin as well brought this on to the extreme.
You mentioned botox. Well yes it is known to help but you would have to have it in all the areas that you sweat and you would have to keep having top uso i don't really think that is the answer.
I think that what we really need to think about is easing the symptoms rather than treating the cause.
There is something you can get online from a site called SCREENFACE which is a theartical website. It is a liquid called NO SWEAT. You can apply it to your face, neck, behind your ears and even in the hairline. It will feel as though your skin is tightening up for a few seconds. It helps control sweat ans stops it running down your face and neck.
it can be worn either under make up or alone.
Another thing which you may find helpful is a spray called Magicool. It is w water spray in an aerosol can. When you shake it, it becomes very cold and is asolutely wonderful to cool you when you are sweating. It is small enough to carry around with you.
We have a pharmacy in UK called oots. Not sure if you have that, but any pharmacy should sell it I would have thought. Or you could always order it from Boots online.
There is also a pillow which stays cool all the time which you could use as a pillow or as a cushion or maybe put behind your back if you are in a car. It is called a CHILLOW> You can get these from many websites. if you just google in CHILLOW you will get all the sites who sell them online.
There is also something called KOOLPACK These can be purchased from any first aid or medical supply site. They are not expensive.
It is a little bag with powder/crystals in. If you bang hard on the centre of it it becomes icy cold and stays cold for about 20 minutes. if you put this on your head, forehead, neck, back, wherever you want it, it will cool you and stop you sweating.
I would not suggest you attempt to stop your antidepressants because faced with the choice of depression or sweating, I think terribble as the sewating is, you would not want the depression back. it would be pointless trying to go onto a different antidepressant because they all have this side effect unfortunately.
You might well get some relief from some of the thing i have suggested however.
i do hope this had helped you.
Lots of love
