Sorry to hear you are in a very rough stage. I know exactly how you are feeling, as I have been there as well, along with many of us.
I felt especially awful in the first several months, which you seem to be going through as well. I must say though, this will become much easier to deal with. In the beginning months of my crash, I got weaker and weaker and had such heavy brain fog, I was bedridden and could barely stand to move, which is a tough state to be in when you have horrible insomnia from the finasteride to begin with. Still, it seems most everyone here is able to make some progress in terms of managing their everyday existence, myself included. Unfortunately, there are some who are not so fortunate, but that does seem to be only the most extreme cases. It stands to reason you will make progress with each passing day, so long as you treat your body well.
Some others have mentioned a few things that have improved their situation, such as: vitamin d, vitamin b3, eating a clean and fresh diet consisting of vegetables are protein etc., but avoiding all of the sugar and crap. I also tried a nice fish oil and it did help my cognition, I feel. I do love apple cidar vinegar as well, and it seems to have improved my sleep in small doses. I eat light meals and feel better when I do, and a nice, light walk can be helpful. If you want to try something a bit unique for digestion, you can go to whole foods and buy some wormwood and black walnut, and drink small morning cocktails. There are lots of things you can try really, and I am sure others who have more experience will have useful advice for you as well.
This has post finasteride crash has been something so awful, I never could have imagined, and I am sure we can all relate. Still, we fight on. Our cause is moving forward all the time. We have Lawyers going after Merck and their CEO Kenneth “Darth” Frazier, we have some solid media awareness thanks to Second Ammendment, Broken Pecker, and Domino, just to name a few, and we have a nice handful of medical professionals becoming more involved with advancing our cause of finding the precise root cause of why we have persistent damage from finasteride, as well as an effective way to treat our many issues. I am sure you have seen, but the PFS Foundation has some updates about upcoming projects, and they are now accepting donations. Also, AWOR and his team continue to work their asses off researching our issues. So, clearly, if we are all going to go down from this syndrome, we are going to go down swinging.
Look, I know this is one of the most bizarre and crummy states we could possibly be in, but there is hope. The potential reward is so amazing, I can practically taste it, but we are not there yet. We have to stick together, and stay organized!, and if we do, we have a fighting chance. Hang in there man. We are all here for you. Perhaps you could try having a small amount of MACA to see if it slowly helps your situation, maybe once a week. Just be careful, take it easy, do not panic, and make sure you rest your body. Resting your body is crucial. Take care of yourself.
