I was under the impression that its always a safe practice with or without tolerance to take a small dose (0.5mg without 1mg-2mg with tolerence) if using Tramadol to get high or Soma which both are capable of producing seizures.
Be that as i've been scripted clonazepam since 04' at 4mg/day and i've never had any bad reactions from abusing/getting high on tramadol nor soma and with tramadol I would take about half gram a day 500mg (didn't need more) and with Soma have done about 3g+ so about 10 pills a day b/c I take 3 for a dose at min, mostly 3.5 or 4 and repeat this 2-3x day, it amazes even myself when I see the next day how much Soma I went through in one day.
