Orals for me was a dose pack. 1st day is 6 or 7 pills total, dropping 1 each day till 1 on the last day. Worked. Forget name of dose pack. Dr said it was strong as 1 gram of IVSM 3x. Worked. Legs stopped jumping at night while trying to sleep. 2 months later & spasms/jolts are back at night (always spasm hard during day, night time ones were new). I'll ask for another dose pack next month.
