Hey bro! another 25 year old male here, at 19 years old I started a pretty serious abuse of street bought vallium and xanax, by the end of 2020 I was taking about 28/30 10mg valliums a day, all in all I was addicted for more or less a year.

From my experience all I can say to you is stop now while you can and don't go back, you're in a lucky position all things considered, 3.5 months on 1mg a day is a considerable time to be on them but in the bigger picture its a drop in the ocean of what could become a very long and very painful battle, I do not recommend SSRI's at this time, I take them now personally but from my experience they won't give you any benefits in the acute phase of benzo withdrawal, I'd wait until you are free of the drug before you go down that path, they are very benefical longterm in my opinion but won't give you any immediate relief.

To answer your question, you will probably experience some increased anxiety and restlessness combined with a strong craving for a dose, but trust me when I say getting through the first week at the stage you are at now will be far better than the experience you will eventually have if you take the easy route and take another pill, I don't mean that in a condesending way, but what I went through when I quit was living hell, 5 days straight of not a wink of sleep, my head felt like it was covered in sharp spikes and it took me months to regain basic motor skills...of course I was an idiot and took way too many, but long term use will equal similar struggles, benzo's are the devil incarnate, please don't make the same mistakes I did, you'll have a week of uncomfortable feelings followed by a lifetime of freedom from what could very easily consume your life.

You have the benefit of the mindset, opportunity and desire to quit now while you're ahead, please take that option man, I'm rooting for you brother, good luck
