How long have you been on low carb? Do you re-feed/carb up? You need to realise that there are a million variables that may be of importance..
I personally would NOT be worrying about sweet cravings when on a carb restricted diet (i personally dont crave to bad even on zero carbs, but hey) - and i certainly would not be concerned with my recovery if all signs pointed to an ample recovery.
By all means use tamox next time sure, but i doubt that is the issue. Cravings pass - man up.
If you have been on a low carb and carb up WITH sugary foods (as is common for a fast insulin response and peak anabolism) this can increase cravings, if you are not carbing up, this can too.. if you have a slightly out of whack E:T ratio - i am sure this can help (increase cravings for sweets).. but you either need to be a whole lot more specific in training, diet, supplement and pharmacology use over the past month, OR you need to work it out for yourself.. Sorry if this sounds harsh.
I personally won't be working through all the aforementioned variables as it will simply take too long for a forum post for my own taste.. But it hopefully gives you an idea of the depth of which something as benign as a sugar craving can go.. IMO at least.
Shit - maybe you need some sweets for a day!
