Pre and post supplementation M-Carn was 25.9 ± 4.3 and 41.3 ± 5.5 mmol.kg-1 dry muscle and M-Tau 28.1 ± 7.1 and 22.6 ± 7.0 mmol.kg-1 dry muscle. Despite the 20% fall in M-Tau, values of M-Tau remained within the normal physiological range. Before supplementation M-Tau was negatively correlated with M-Carn, evidenced by subjects with the highest M-Carn having the lowest M-Tau, expressing a similar relationship to that reported earlier. The same negative relationship was preserved after b-Ala supplementation and during the 6 weeks recovery from supplementation (overall data: [M-Tau] = -0.634 · [M-Carn] + 46.6; r = 0.72; p<0.001; n = 28).

From personal experience, I do yet know that side effects like cramping and muscle ache are very real once you start taking several grams of beta-alanine per day.
I, thus strongly suggest not to go overboard on beta-alanine, because I suspect higher daily doses (in the range of 5g+) would have resulted in a severe depletion of muscle taurine which would interfere with "the control of ionic ﬂux", and taurines effect "effect on osmoregulation" (Di Pasquale. 2008. 311) and thus trigger exactly those undesirable side effects which asked me riddles, back in the day.
