I was taking Lyrica 50 mg for 3 days, starting 2 times a day for 1 day then 3 times a day for 2 days, the third day I only took it once. I also took Sumatriptan 20 mg nasal spray, twice on that first day, once on the second day, and none on the third day. On this third day I took Maxalt 10 mg, I was taking these meds for cluster headaches. This is still the third day, Now I have started Prednisone 20 mg, taking 3 today, and I am not going to be taking any of the other meds, for they are not working. I'm just sticking with the prednisone till gone. How long do I have to wait to have alcohol?
