Clonidine - I started 0.2mg clonidine and it put me in the bed. BP fell by 90 190+ to 110+.

I'm not sure what your question is, but I have been taking Clonidine for many years. Maybe I can help.
I have erratic BP. Sometimes it is high, sometimes it's low. Like you my doc started me on 0.2 mg. twice a day. He didn't warn me about side effects. As I was driving to work, I woke up driving on the wrong side of the road! Years later, I learned to only take 0.1 mg. as needed, up to 4 times per day. In fact, I have used it as a sleep aid at night.
It's a good drug, but doctors should not start people on 0.2 mg. It's just too much.
