Bad reaction to Pulsatilla 1M

Would love a professional's opinion on this or anyone who has had a similar reaction. Around a month ago I went to a respected homeopath to help me out with some post period pains. He prescribed pulsatilla 1M. 2 days later I woke up in a panicked state with nausea and diarrhea. Didn't think much about it and went back to sleep. A few days later I was trying to fall asleep and I was suddenly woken up with an ill and horrible filling of panic, nausea, diarrhea. This continued for about a week where I felt SO unbelievably horrible with horrible horrible panic and anxiety. Shivering,chills,no appetite. Would wake up suddenly every night with nervous energy and restlessness. This went on for a week.I had an appointment to see him at the end of the week, I explained my distress and bad reaction and he gave me nat-m 30 that he said will help calm me down and help with my sleep. It calmed me down for a few hours but it did nothing for my sleep.I ended up sleeping 1 hr that night.and woke up with the same panic again. I called him the next day and he gave me lyc 1M. That did help with my sleep and I have been sleeping well (not much but well) for the past 2 weeks.My symptoms have been slowly improving ever since.I would like to know if this is a possible reaction to the pulsitilla, is it maybe because my body was overly sensitive to the remedy?
