I have been on 10 mg. of valium for 30 years and about 6 years ago, the psychaitrist told me to take 30 mg.  What do I do, can I do it myself with a guide from a book or doctor, or what?  I took off 5 mg. and it was no problem, but I know that as you go down, you have trouble or whatever.  In fact, I went to 20 mg. about 5 months ago without any problem, but when back to 30.  Now I am on 25 mg.
His understand your concern. Yes it is possible but for that you have to maintain proper schedule. Like starting from 25 mg of Valium you have to cut down 5 mg every week. I prefer in my patient like that 1st week 25 mind week 20 GRD week 15 mg ...and gradually shift to 5 mg.if you require then there are also some add on medication which fulfill and treat with Chat Doctor. Treatment of underlying disorder is also must for that you need consultation to psychiatrist. Sometimes psychological illness need to treat on 1st priority. Still have query then feel free to ask. Happy to help you further. Thank you.
