This is too bad.
We really have to much faith in 'pills' when they are obviously just a temporary fix for something underlying.
I had a physical ailment that was hard to diagnose, the doctors could be bothered.
Finally I 'fixed myself' simply by sleeping normal hours, quitting the red-bull, and quit my job and took some time away from stress. That did it.
Scary: not a single doctor asked me about my habits! If they did, they would have found I was sleeping 5 hours a night, drinking 3 redbulls a day, and max-stressed. The answer was obvious to any fool! But several doctors missed it!
Good luck with your issue.
