I was IP when I was young-ish think 1992 and then again 2010.. Alot has changed in just that "relatively" short amount of time in regards to medication and just the way CBT and DBT is used. The majority of people are only IP for at most a couple weeks not months anymore (excluding first time ECT patients) Life long IP is still out there , but advances in treatment has certainly decreased the % of people who need to be IP for most of there lives.
I am lucky.
