Glad to hear both the Huel and the side-effects are working well for you! Like any massive change in diet, the body definitely doesn’t greet it with open arms initially, but the boat steadies eventually.
Beware: I’ve now been drinking 2 Huels almost every day for about 6 months and am now fairly well addicted to it. Not having to prepare nutritionally balanced meals during the day is huge. Yes, I sometimes wake in cold sweat from a nightmare about that first dreadful week, but it’s all worth it in hindsight. Maybe we should make a Huel support group?
