Familial periodic paralysis symptoms and conditions

For 59 years I have had familial periodic paralysis. Lately my potassium level has been down. This problem started after taking albuterol for copd.
I take two puffs every 8 hrs .I could not understand why I was getting paralysis as it had tapered off considerably the last 15 years and I have not had paralysis at all for 3 years until the last 4 months. Now I will have to take small amounts of potassium every night but less than when I was younger.
The Albuterol has helped me considerably!
