How much is 120mg a day for the past 60-90 days considered & how hard is the detox?

So I started 7OH tabs about 11 months ago and I started with just like 7mg tabs every now and then and the last month or two it has peaked to like 120mg a day. Needless to say I’m getting off. Too expensive and not healthy.

I’m tracking starting today and plan to taper for maybe a week or two. I have access to 10mg perc in case I should just switch to that at some point and ween off that. I used to use perc monthly like 30-40 pills a month be on for 2 weeks and then off for 2 weeks.

Could use plenty of advice on what I’m in for and how long it will take to get out of my system and not dependent or craving.

Let me know. From what I’m seeing I’m like a medium user and have been at that level for only about 1-2 months now.

Thanks all!
